Synthesis and characterization of phosphite-containing cobalt(III) complexes obtained via disproportionation reactions of pentacoordinate mononitrosyl derivatives. Crystal structure of trans-bis(isothiocyanato)tetrakis(triethyl phosphite)cobalt(III) tetraphenylborate

The disproportionation reactions of Co(SCN)2 (in the presence of P(OMe)3) and [Co(NCS)L3(NO)]+ (L = P(OEt)3 or PhP(OEt)2) species have been examined and have led to the synthesis of the first cobalt(III) complexes with the donor-atom set X2L4 (X = pseudohalogen; L = monodentate phosphite). Both the cis- and the trans-[Co(NCS)2L4]BPh4 isomers were isolated and characterized, and the crystal structure of trans-{Co(NCS)2[P(OEt)3]4}BPh4 was determined. Crystals are monoclinic, space group P21/c, with Z = 4 in a unit cell of the following dimensions: a = 19.05 (2) ?, b = 13.25 (1) ?, c = 27.46 (3) ?, β = 109.86 (7)°. The structure was solved by the heavy-atom method from automated diffractometer data and refined to R = 0.0935 for 3199 reflections.
