SOME PALLADIUM(II) COMPLEXES OF 1,2-BIS(MERCAPTO)ORTHOCARBORANE

Abstract

Abstract Coordination compounds of the type Pd(DMC)L and [Pd(DMC)2]C where DMC is 1,2-bis(mercapto)-o- carborane, L = 1-diphenylphosphino-o-carborane (HPC), 1,2-bis(diphenylphosphino-o-carborane (NPC) and C [dbnd] H+ or tetraethylammonium cation, have been prepared and characterized by IR, Raman and electronic spectroscopy, magnetic and conductivity measurements. DMC behaves as a bidentate sulphur donor ligand and the tertiary phosphine (HPC) and ditertiary phosphines (DPC and NPC) are bonded through the phosphorous atoms to produce a planar PdS2P2 skeleton of C2v symmetry.
