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.

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.
