Penta-carbon-yl{3-[(2S)-1-methyl-pyrrolidin-2-yl]pyridine}tungsten(0).

ABSTRACT: The title compound, [W(C(10)H(14)N(2))(CO)(5)], contains five carbonyl ligands and a nicotine ligand in an octa-hedral arrangement around the tungsten atom. The metal atom shows cis angles in the range 87.30 (16)-94.2 (2)°, and trans angles between 175.2 (2) and 178.1 (4)°. The W-CO bond trans to the pyridine N atom [1.987 (6) Å] is noticeably shorter than the others, which range between 2.036 (3) and 2.064 (3) Å, possibly due to the well-known trans effect. The distance between the W atom and the pyridine N atom is 2.278 (4) Å.
