According to X-ray diffraction data, the nickel complex [Ni(Bu3P)(2)(NCS)(2)] has a square-planar structure with the two phosphine ligands trans to each other and the thiocyanate ligand coordinated by the nitrogen atom. The IR and H-1, C-13, and P-31 NMR data show that the same structure is preserved in solutions. The catalytic activity of the complex in hydrosilylation of 1-hexene with chlorohydrosilanes HSiMe3-nCln varies in the series HSiCl3 > HSiMeCl2 > HSiMe2Cl. The reactions of the complex with hydrosilanes involve substitution of the anionic ligand and formation of silyl complexes.
