Bis(thiophosphinoyl)amines and their neutral cobalt(II) complexes, containing stable tetrahedral CoS4 cores. Crystal structures of NH(SPMe2)(SPPh2) and [Co{(SPMe2)(SPPh2)N}2]

The compound NH(SPMe2)(SPPh2) was prepared using a new method, i.e. the reaction between Li[HN(S)PPh2] and Me2P(S)Cl in a diethyl ether-n-hexane mixture. The complex [Co{(SPMe2)(SPPh2)N}2] was obtained by the reaction of CoCl2·6H2O and K[(SPMe2)(SPPh2)N] in methanol. The crystal and molecular structure of both the free acid NH(SPMe2)(SPPh2) and its cobalt(II) complex [Co{(SPMe2)(SPPh2)2N}2] were determined using X-ray diffractometry. The acid exhibits an anti conformation of the sulfur atoms in the SPNPS system and dimeric pairs are formed in the crystal through N(1)-H(1) ... S(2a) [2.43(9) A] hydrogen bonds, which involve only the sulfur atom of the S=PPh2 group of each molecule. The cobalt complex consists of discrete, monomeric molecules, with isobidentate ligands [average Co-S 2.32(1), average P-S 2.031(5) A] and a distorted tetrahedral CoS4 core (S-Co-S range 102.7-117.7°). The structures of both the free acid and its cobalt(II) derivative are discussed in relation with other bis(thiophosphinoyl)amines and metal complexes containing a CoS4 core.
