Abstract

In a new polymorph of acetato (2, 2′-{iminobis [(E)-propane-3, 1-diylnitrilomethylidyne]} diphenolato) cobalt (III),[Co (C20H23N3O2)(C2H3O2)], in the space group P21/c, the CoIII ion is six-coordinate, with unequal Co—Ophenolate distances that average 1.908 (12) Å and more similar Co—Nimine distances averaging 1.937 (4) Å. The acetate ion occupies the sixth coordination site and forms an intramolecular hydrogen bond (H⋯ O= 1.95 Å) with ...
