Abstract
Carbon monoxide or cyclohexyl isonitrile (L) react with the dinuclear five-coordinated derivatives of 1,1,1-tris(diphenylphosphinomethyl)ethane, (triphos), [(triphos)Co(μ-X) 2Co(triphos)](BPh 4) 2 (X = halide) to give complexes of formula [(triphos)Co(L)X]BPh 4. The latter are rare examples of paramagnetic cobalt(II) carbonyl complexes. The molecular structure of [(triphos)Co(CO)Br]BPh 4 has been determined from counter diffraction data. The crystals are monoclinic, space group P2 1/ a with cell dimensions a 20.225(8), b 20.664(9), c 13.301(5); β 97.24(5)°, D c = 1.338 g cm −3 for Z = 4. Full-matrix least squares refinement led to the conventional R factor of 0.057 for 3648 observed reflections. The molecular structure consists of five-coordinate [(triphos)Co(CO)Br] + cations of intermediate geometry and BPh − 4 anions.
