The molar conductivities show that the complexes are electrolytes. The IR spectra suggest that the ligands are tetradentate in all cases, whilst the electronic spectra together with magnetic moment data suggest octahedral geometry for all the complexes (except copper complexes). In all these complexes, the oxime <span style="font-size:14.0pt;font-family: Arial;mso-fareast-font-family:" times="" new="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">(=N-O) <span style="font-size:14.0pt;font-family:" times="" new="" roman";mso-fareast-font-family:="" "times="" roman";mso-ansi-language:en-us;mso-fareast-language:en-us;="" mso-bidi-language:ar-sa"="">group acts as a bridging function to give dimeric structures.</span></span></span>
