摘要：

The cobalt(II) complex of 3-methoxy 2-hydroxybenzaldehyde, L2Co(H2O)(2), reacts with lanthanide nitrates to afford dinuclear complexes L2Co(H2O)(2)Ln(NO3)(3). An X-ray diffraction study of L2Co(H2O)(2)Pr(NO3)(3) has been performed. It crystallizes in che monoclinic space group P2(1)/c, in a cell having the dimensions a = 9.4832(11) Angstrom, b = 18.319(2) Angstrom, c = 14.6226(13) Angstrom and beta = 106.121(12)degrees and Z= 4. The magnetic properties of L2CO(H2O)(2)Gd(NO3)(3) revealed chat a ferromagnetic interaction occurs between the Co2+ and Gd3+ ions. (C) Academie des sciences/Elsevier, Paris.
