Sa. Macgregor et al., WHY NICKEL(II) BINDS CO BEST IN TRIGONAL BIPYRAMIDAL AND SQUARE PYRAMIDAL GEOMETRIES AND POSSIBLE CONSEQUENCES FOR CO DEHYDROGENASE, Inorganic chemistry, 33(16), 1994, pp. 3616-3618
Ni(II) does not normally bind CO. We show how a judicious choice of li
gand set and coordination geometry can make this possible as in NiCl2(
PMe3)2-(CO). The two factors that favor CO binding are the TBP geometr
y and the presence of donor ligands. The relevance to CODH, a Ni-conta
ining enzyme, is discussed.
