Abstract:

The reaction of NiCl2.6H20 A with bis-diphenylphosphino carboranes B with 1, 2, and 3 Br atoms attached to the carborane nucleus yielded complexes containing two molecules of bis-phosphine and one of NiCl2. The substitution of PtII and PdII for the NiII in A also resulted in stable complexes. The reaction of unbrominated B with A yielded the 11 complex C6H54P2C2B10H10NiCl2 which converted to the corresponding 21 complex upon refluxing in ethyl acetate. The product compounds were examined chemically and their IR spectra, UV spectra, and magnetic moments were obtained. A square planar molecular configuration is tentatively assigned to the 21 type complexes.
