title: Pentacarbonyl(4-phenylpyridine)tungsten(0) and pentacarbonyl(2-phenylpyridine)chromium(0).
abstract: In pentacarbonyl(4-phenylpyridine)tungsten(0), [W(C(11)H(9)N)(CO)(5)], the molecules have mm site symmetry and the pyridine ligand, with m symmetry, is completely planar. In pentacarbonyl(2-phenylpyridine)chromium(0), [Cr(C(11)H(9)N)(CO)(5)], the molecules are in general positions and the phenyl and pyridine rings of the ligand are twisted by 67.7 (3) degrees with respect to one another by rotation about the C-C bond joining them. In both compounds, the axial M-C(carbonyl) bond trans to the M-N(ligand) bond is significantly shorter than the equatorial M-C(carbonyl) bonds.
