Abstract

Two new chromium(V)-nitride complexes with a coordination sphere completed by bidentate ligands have been synthesized and structurally characterized. Bis(2-methylquinolin-8-olato)nitridochromium(V), [Cr(C10H8NO)2(N)], has the coordination sphere completed by an equatorial N2O2 set of ligators. The compound crystallizes with the five-coordinate complexes at sites with twofold rotational symmetry and all Cr-N bond directions aligned with the crystallographic b axis. Nitridobis(2-sulfidopyridine N-oxide)chromium(V), [Cr(C5H4NOS)2(N)], crystallizes with the molecules on general positions and has an equatorial S2O2 coordination environment, which is unprecedented among nitride complexes of the first-row transition metals. In both systems, Cr[triple-bond]N bonds are short at ca 1.56 A.
