Carbon monoxide or cyclohexyl isonitrile (L) react with the dinuclear five-coordinated derivatives of 1,1,1-tris(diphenylphosphinomethyl)ethane, (triphos), (BPh4)2 (X=halide) to give complexes of formula BPh4.The latter are rare examples of paramagnetic cobalt(II) carbonyl complexes.The molecular structure of 1/a with cell dimensions a 20.225(8), b 20.664(9), c 13.301(5); β 97.24(5) deg, Dc=1.338 gcm-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 + cations of intermediate geometry and BPh4- anions.
