Cobalt tris(diethyldithiocarbamate) is the coordination complex of cobalt with diethyldithiocarbamate with the formula Co(S2CNEt2)3 (Et = ethyl). It is a diamagnetic green solid that is soluble in organic solvents.[1]

Synthesis, structure, bonding

Cobalt tris(dithiocarbamate)s are typically are prepared by air-oxidation of mixtures of dithiocarbamate salts and a cobalt(II) nitrate.[2] Cobalt tris(diethyldithiocarbamate) is an octahedral coordination complex of low-spin Co(III) with idealized D3 symmetry. The Co-S distances are 267 pm.[3]

Reactions

Oxidation of Co(Et2dtc)3 occurs at mild potentials to give the cobalt(IV) derivative.[2]

Treatment of Co(Et2dtc)3 with fluoroboric acid results in the removal of 0.5 equiv of ligand giving a binuclear cation:[4]
