Purple prismatic crystals of the title compound, [Co-2(C3H6NS2)(4)(C8H11O2P)(2)](PF6)(2), were obtained by repeated recrystallization of trans-[Co(C3H6NS2)(2)(C8H11O2P)(2)]PF6 from CH3CN/Et2O and then from MeOH/CH2Cl2; during recrystallization one of the P(OMe)(2)Ph ligands was dissociated from the Co-III center and the resulting Co-III complex fragment underwent dimerization. The complex cation has a dinuclear structure bridged by one S atom of each of two of the N,N-dimethyldithiocarbamate ligands, and has crystallographically imposed C-2 symmetry. Two P(OMe)(2)Ph ligands are coordinated at the transoid positions of the Co-2(mu-C3H6NS2)(2)(C3H6NS2)(2) moiety, with Co-P bond lengths of 2.1921 (11) Angstrom.
