Synthesis and Reactivity of Hybrid Phosphido- and Hydrosulfido-Bridged Diruthenium Complexes: Transformations into Diruthenium and Tetraruthenium Complexes Bridged by Phosphido and Sulfido Ligands

Hydrosulfide complexes of the transition elements: diverse roles in bioinorganic, cluster, coordination, and organometallic chemistry

Molecules containing transition metal hydrosulfide linkages are diverse, spanning a variety of elements, coordination environments, and redox states, and carrying out multiple roles across several fields of chemistry.

A dipotassium 1,2,4-diazaphospholide dianion radical as an organometallic building block: the first 1,2-diaza-4-phosphine ruthenocene

A persistent dipotassium 3,5-diphenyl-1,2,4-diazaphospholide dianion radical {K+2[(3,5-Ph2dp)]˙2-} (2) was synthesized and investigated by EPR analysis and magnetic susceptibility measurement, and it can be used as a transfer agent for the preparation of an unusual 1,2-diaza-4-phosphine ruthenocene (4) with exclusive σ(P)-coordination. A plausible mechanism for the formation of 4 was proposed as one that involves a reactive radical intermediate {K+[(η5-CpMe5Ru)(σ(P),σ(C)-(3,5-Ph2dp)˙]-)} (K+[5A˙]-) with σ(P)-coordination due to the high spin density (SD) at the phosphorus (σ2λ3) atom.

In search for new bonding modes of the methylenedithiolato ligand: novel tri- and tetra-metallic clusters

Photolysis ofarachno-[(Cp*Ru)₂(B₃H₈)(CS₂H)] in the presence of [Re₂(CO)₁₀] produced [(Cp*Ru)₂B₃H₅(CH₂S₂){Re(CO)₄}₂], with a planar 8-membered ring containing heavier transition metals and a main group element.
