Activation of CS2 by a “masked” terminal nickel sulfide

Activation of carbon disulfide (CS2) by “masked” terminal nickel sulfide, [K(18-crown-6)][(LtBu)Ni(S)], gives a trithiocarbonate complex. This result confirms the nucleophilicity of the sulfide ligand and expands the scope of reactivity for late metal sulfides.

On the coordination non-innocence of antimony in nickel(II) complexes of the tetradentate (o-(Ph2P)C6H4)3Sb ligand

The coordination non-innocence of antimony toward Cl in ClNi(o-(Ph2P)C6H4)3SbCl results from both structural and electronic effects.

Thermodynamics of N–H bond formation in bis(phosphine) molybdenum(II) diazenides and the influence of the trans ligand

Dinitrogen-derived molybdenum alkyldiazenides and alkylhydrazides were synthesized with various trans ligands. The thermodynamics of N–H bond formation were studied both experimentally and computationally.

Supramolecular adducts based on weak interactions between the trimeric Lewis acid complex (perfluoro-ortho-phenylene)mercury and polypnictogen complexes

The adduct formation of the trinuclear Hg Lewis acid [(o-HgC6F4)3] with polypnictogen complexes is described focusing on the varying interaction modes based on the nature of the donor atoms P, As, Sb or Bi.

Multi-electron redox processes at a Zr(IV) center facilitated by an appended redox-active cobalt-containing metalloligand

The reactivity of a reduced heterobimetallic Co−I/ZrIV complex with a series of azido and diazo reagents is explored to demonstrate the feasibility of facilitating two-electron redox processes at a formally d0 Zr(IV) center using the appended Co fragment exclusively as an electron-reservoir.

Monoanionic bis(carbene) pincer complexes featuring cobalt(I–III) oxidation states

The synthesis and characterization of a series of cobalt complexes featuring a pincer bis(carbene) ligand of the meta-phenylene-bridged bis-N-heterocyclic carbene (ArCCC, Ar = 2,6-diispropylphenyl or mesityl) are reported.

A doubly deprotonated diimine dioximate metalloligand as a synthon for multimetallic complex assembly

An electrocatalytically active cobalt diimine dioximate metalloligand was prepared and explored as a precursor for a variety of multimetallic complexes with Co–Zn, –Cd, –Mn, and –Ru coordination.

Supramolecular aggregation of Ni(salen) with (C6F5)2Hg and [o-C6F4Hg]3

Organomercurials (C6F5)2Hg and [o-C6F4Hg]3 interact with Ni(II)-salen to form adducts held by arene-perfluoroarene and hydrogen bonding interactions, as well as interactions between Hg, the salen ligand, and Ni.

N-heterocyclic phosphenium and phosphido nickel complexes supported by a pincer ligand framework

A tridentate ligand framework containing a central N-heterocyclic phosphenium cation (NHP+) has been coordinated to nickel. Among the compounds reported is a series of [(PPP)Ni]20/+/2+ dimers in three different redox states.

About this collection

The Dalton Transactions UC Berkeley Lecture is given annually to an outstanding young investigator in the general field of inorganic chemistry. Previous recipients include Jilliam L Dempsey, Kit Cummins, John Hartwig, Geoff Coates, Paul Chirik, Dan Mindiola, Teri Odom, Daniel Gamelin, Trevor Hayton, Christine Thomas, Mircea Dinca, and Alison Fout. This themed collection highlights some of the excellent work that the past recipients have published recently in Dalton Transactions.

The 2018 - 2019 recipient of the Dalton Transactions UC Berkeley Lecture is Brandi M Cossairt (University of Washington). Her lecture was entitled "The Chemistry of Nanoscale Phosphides: Building Complex Inorganic “Molecules” with Atom-Level Precision"
