Abstract

Complexation of bis(3-phenyl-1-azaazulen-2-yl)amine with Zn(OAc)2 and Ni(OAc)2 was investigated, and four-coordinate bis-chelate complexes, M(II) bis[(3-phenyl-1-azaazule-2-yl)(3-phenyl-1-azaazulen-2-ylidene)aminate] (M = Zn, Ni), were obtained. Complexation of bis(1-azaazulen-2-yl) sulfide with CoCl2 gave 2 : 1 ligand-metal complex as major product and complexation of bis(3-iodo-1-azaazulen-2-yl) sulfide with CoCl2 gave 1 : 1 ligand-metal complex.
