Abstract

Some Ni(II) complexes with 5,7-dicloro-8-aminoquinoline (dcaq), 5,7-dibromo-8-aminoquinoline(dbaq) and 5,7-diiodo-8-aminoquinoline(diaq) are described. The compounds are of stoichiometry NiL2X2(L= dcaq, dbaq, diaq; X= NO-3 and L= dbaq; X= Cl-, Br-, I-, NCS-) and NiLX2·H2O(L= dcaq, diaq; X= Cl-). The electronic spectra and magnetic susceptibility data at room temperature, are consistent with octahedral geometry for the Ni(II) in each compound. I.r. spectra show the presence of ionic and bridging nitrate groups in the compounds NiL2(NO3)2(L= dcaq, dbaq, diaq) and we assign them polymeric structures. Polymeric structures with bridging chloride are proposed for the compounds NiLCl2·H2O(L= dcaq, diaq) and monomeric octahedral structures for NiL2X2(L= dbaq; X= Cl, Br, I, NCS). © 1983.
