Reaction of 4-bromo-2-(((5-chloro-2-hydroxyphenyl)imino)methyl)phenol (H2L) with Cu(OAc)2·4H2O or VOSO4·3H2O and 2,2′-bipyridine (bipy) or 1,10-phenanthroline (phen) in a 1 : 1 : 1mol ratio led to [CuL(phen)] and [VOL(bipy)] which have distorted square pyramidal and octahedral geometries, respectively. The compounds were characterized by elemental analyses, FT-IR, UV–Vis, TGA, and X-ray diffraction. Their thermolyses have three stages: phen or bipy removal, separation of H2L minus chloride and bromide of H2L, and complete thermal decomposition to the metal oxide.
