| Abstract: | Summary The preparation and spectral properties of five copper(II) complexes of semicarbazones, derived from 2-hydroxy-naphthaldehyde (NPSCZ), benzoin (BZSCZ) and isatin (ISSCZ) are described. I.r., electronic, e.s.r. 1H and 13C n.m.r. spectra show that the semicarbazone's coordination is distorted trigonal bipyramidal for [Cu(BZSCZ-2H)(H2O)], distorted tetragonal pyramidal for [Cu(NPSCZ)2](ClO4)2 and dimeric for the other three complexes. |
