title: Bis(mu-N,N-dimethyldithiocarbamato-kappa3S,S':S')bis[(dimethoxyphenylphosphane-kappaP)(N,N-dimethyldithiocarbamato-kappa2S,S')cobalt(III)] bis(hexafluorophosphate).
abstract: Purple prismatic crystals of the title compound, [Co(2)(C(3)H(6)NS(2))(4)(C(8)H(11)O(2)P)(2)](PF(6))(2), were obtained by repeated recrystallization of trans-[Co(C(3)H(6)NS(2))(2)-(C(8)H(11)O(2)P)(2)]PF(6) from CH(3)CN/Et(2)O and then from MeOH/CH(2)Cl(2); 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-C(3)H(6)NS(2))(2)(C(3)H(6)NS(2))(2) moiety, with Co-P bond lengths of 2.1921(11)A.
