Themed collection Dalton turns 50 – celebrating our board members past and present
John Dalton – the man and the myth
John Dalton is the “face of inorganic chemistry” in the RSC journal Dalton Transactions. Who was he and what did he do?.
The synthesis and versatile reducing power of low-valent uranium complexes
This synthesis and diverse reactivity of uranium(III) and uranium(II) complexes is discussed.
A cavity-shaped cis-chelating P,N ligand for highly selective nickel-catalysed ethylene dimerisation
The presence of a cyclodextrin cavity in a chelating P,N ligand promotes the exclusive formation of 1 : 1 ligand/metal complexes. A Ni(II) complex of the ligand is a very selective catalyst for ethylene dimerisation as a result of metal confinement.
Anion recognition by halogen bonding and hydrogen bonding bis(triazole)-imidazolium rotaxanes
A novel halogen bonding bis(iodotriazole)-imidazolium axle containing rotaxane is capable of strong halide and sulfate binding in highly competitive aqueous–organic solvent mixtures.
Single-molecule magnet behaviour in a centrosymmetric dinuclear dysprosium(III) complex: sequential differentiation of triple relaxation pathways
A centrosymmetric dinuclear Dy-based complex, Dy2L2(H2L)Cl2(EtOH)2, was successfully synthesised, and exhibits a typical SIM behaviour and unusual triple relaxation pathways.
C(sp3)–H bond activation by the carboxylate-adduct of osmium tetroxide (OsO4)
The carboxylate adducts of OsO4 ([OsO4(X)]−, X− = AcO− and BzO−) were isolated and their structures, physicochemical properties and reactivity were explored. The C(sp3)−H oxygenation mechanism by the carboxylate adducts was discussed based on their kinetics and DFT studies.
From polygons to polyhedra through intermediate structures. A shape measures study of six-atom inorganic rings and clusters
The book of Nature displays a wealth of continuously varying molecular geometries. See what can be done with just six atoms.
Synthesis and photophysical properties of linear gold(I) complexes based on a CCC carbene
New gold carbazolate complexes based on a CCC-type carbene ligand give red photoemitters with sub-microsecond excited state lifetimes.
Umbelliferyloxymethyl phosphonate compounds-weakly binding zinc ionophores with neuroprotective properties
Umbelliferyloxymethyl phosphonates:non-chelating ionophores that A protect rat hippocampal cells from toxic Aβ42 B partition Zn from water to octanol C inhibit Zn promoted aggregation of Aβ42, D delay Zn signaling by FluoZin-3 in neuronal cells.
The influence of alkyl chains on the performance of DSCs employing iron(II) N-heterocyclic carbene sensitizers
DSC photoconversion efficiencies of up to 0.93–0.95% have been achieved for a new heteroleptic iron(II) N-heterocyclic carbene sensitizer employing n-butyl chains.
Gas electron diffraction then and now: from trisilyl phosphine to iso-propyl(tert-butyl)(trichlorosilyl)phosphine
GED has evolved hugely in the 50 years of Dalton Transactions. Combining experimental and theoretical data now allows complicated structures free from intermolecular interactions like iso-propyl(tert-butyl)(trichlorosilyl)phosphine to be revealed.
Selective construction and stability studies of a molecular trefoil knot and Solomon link
A trefoil knot and a Solomon link were successfully prepared based on a carefully selected flexible phthalic diimide ligand and precisely controlled stacking interactions.
Synthesis and DNA interaction studies of Ru(II) cell penetrating peptide (CPP) bioconjugates
The synthesis and biological investigations of the first bioconjugates of ruthenium(II) dipyridophenazine complexes with two different covalently attached cell penetrating peptides (CPPs) is described.
NMR studies of group 8 metallodrugs: 187Os-enriched organo-osmium half-sandwich anticancer complex
Synthesis of this 187Os-enriched organo-osmium azopyridine anticancer complex, has allowed determination of 187Os NMR J-couplings to ligand 1H and 13C, and the 187Os chemical shift. The complex was also characterised by X-ray crystallography and MS.
Getting a lead on Pb2+-amide chelators for 203/212Pb radiopharmaceuticals
Three chelators were developed for potential use in 203/212Pb-based radiopharmaceuticals. Studies probing the coordination chemistry of the metal complexes and radiolabeling capabilities revealed a compound for future study.
New phosphorescent iridium(III) dipyrrinato complexes: synthesis, emission properties and their deep red to near-infrared OLEDs
A resistance to the bathochromic shift was found in a series of Ir(III) dipyrrinato phosphors, which show the deep red to near-infrared emissions, and their OLEDs afforded a peak EQE of 2.8%.
Reactivity of a T-shaped cobalt(I) pincer-complex
A paramagnetic T-shaped cobalt(I) complex, stabilised by a monoanionic NNN pincer ligand, induces reductive bond cleavage and related transformations of small molecules.
Modulation of N^N′-bidentate chelating pyridyl–pyridylidene amide ligands offers mechanistic insights into Pd-catalysed ethylene/methyl acrylate copolymerisation
Careful ligand design led to the detection of either an unprecedented, stable, 4-membered palladacycle or an off-cycle catalyst degradation product.
High denticity oxinate-linear-backbone chelating ligand for diagnostic radiometal ions [111In]In3+ and [89Zr]Zr4+
A potentially decadentate oxinate-containing ligand was synthesized and assessed through solution thermodynamics studies, concentration dependent radiolabeling and serum stability assays with [nat/111In]In3+ and [nat/89Zr]Zr4+.
Outside the box: quantifying interactions of anions with the exterior surface of a cationic coordination cage
The binding of anions to the surface of an octanuclear coordination cage HW, which carries a 16+ charge, in aqueous solution, was studied using a fluorescence displacement assay with fluorescein as the probe.
An unusual Pd(III) oxidation state in the Pd–Cl chain complex with high thermal stability and electrical conductivity
A thermally stable and highly electrically conductive Pd(III) 1D complex [Pd(dabdOH)2Cl]Cl2 was newly synthesized.
About this collection
2021 is a huge milestone for Dalton Transactions – the publication of its 50th volume! Since its launch in 1972—then named Journal of the Chemical Society, Dalton Transactions—the journal has published over 45,000 articles featuring contributions from over 100 countries across six continents. Dalton Transactions is a truly international journal with an international readership and this global reach is a result of the work of our many editorial and advisory board members over the years.
This themed collection celebrates the high quality research published in Dalton Transactions authored by our board members past and present. The breadth and diversity of the field of inorganic chemistry is illustrated by this collection, as well as the new avenues being explored.
Further articles will be added to the collection as they become available. I hope you enjoy reading these articles and here’s to another 50 years of Dalton Transactions!
