It is a diamagnetic green solid that is soluble in organic solvents.

[1] 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.

[3] 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]
