Abstract
Nine complexes of copper(II), cobalt(II), Ni(II), and Zn(II) chlorides with naphtho[1,2,-c][1,2,5]oxadiazol-9-ol (HL1), naphtho[1,2-c][1,2,5]thiadiazol-9-ol (HL2), and naphtho[1,2-c][1,2,5]selenadiazol-9-ol (HL3) have been synthesized, isolated in the crystalline state, and studied by physicochemical methods. The composition of the complexes in solutions as been determined and their stability constants have been calculated from spectrophotometric data. The electronic structures of the ligands and complexes have been calculated by quantum-chemical methods. The crystal and molecular structure of HL2 has been determined by X-ray crystallography.
