The complexes of general formula Cu(H2L) (II); [CuLn(L)(NO3)(H2
O)n] (where H4L=N,NI-bis[2-hydroxy(3 carboxynaphtalidene)] ethylenediamine; Ln: Nd, n=6 (III); Eu, n=4 (IV); Gd, n=6 (V) have been synthesized and investigated by different methods (IR spectroscopy, TG analysis and magnetochemistry). The coordination set of complex generators are Cu(N2O2) and Ln(O89). The effective magnetic moment values, µeff,at 300 K are: 1.78 (II), 3.22 (III), 6.44 (V) B.M. The temperature dependence (300-2 K) of magnetic susceptibility of [CuNd(L)(NO3)(H2O)6] indicates the antiferromagnetic interaction between metal ions.
