Abstract

Potassium cobaltates K+CoLsL' -(L = Me3P, L' = N2, olefin) react with SnCl(C6H5)3 or GeBr(CeH5)3 to give tetracoordinate complexes containing Co-Sn and Co-Ge bonds. Crystal and molecular structures of two single crystals were determined. They show tetrahedral molecules Co[Sn(C6H5)3][P(CH3)3]3 in different packing order. Both tetra-coordinate compounds take up small ligands thereby completing their 18-electron valence shells in compounds Co[E(C6H5)3]L3L' (L = (CH3)3P; E = Ge, L' = CO; E = Sn, L' = CO, C2H4). A sparingly soluble paramagnetic adduct Co[Sn(C6H5)3]L4 is believed to contain a tin-bonded phosphane.
