Tricarbonyl(η6-pyridine)chromium(0)

Abstract

The molecular structure of tricarbonyl(η 6 -pyridine)chromium(0), [Cr(CO) 3 (C 5 H 5 N)], is presented here. The Cr atom is bound to the pyridine ring via the π-electron system and is situated directly below the heteroarene ring centre. The pyridine ring is slightly distorted compared to free pyridine and the distance from the Cr atom to the plane of the pyridine ring is 1.698 (2) A. The tricarbonyl moiety adopts an eclipsed conformation with respect to the pyridine ring atoms
