The α-diimine ligands Ar{single bond}N{double bond, long}C(R){single bond}C(R){double bond, long}N{single bond}Ar (ai, bi, c) react with CrCl3(thf)3 1 in the presence of zinc to give new diamagnetic tetrahedral chromium (II) complexes supported by α-diimine ligands 2ai (i = 1-2), 2bi (i = 1-2) and 2c in good yields. All compounds were characterized by NMR and IR spectroscopy. The solid-state structure of 2b2, which crystallized in the Orthorhombic space group P212121 with unit cell parameters a = 11.825(5) A?, b = 12.034(4) A? and c = 16.393(8) A?, was established by X-ray crystallography.
