Abstract
Two new dicyanamide bridged 1D polynuclear copper(II) complexes [Cu(L1){µ1,5-N(CN)2}]n (1) [L1H = C6H5C(O)NHN{double bond, long}C(CH3)C5H4N] and [Cu(L2){µ1,5-N(CN)2}]n (2) [L2H=C6H5C(O)CHC(CH3){double bond, long}NCH2CH2N(CH3)2] have been synthesised and structures of both the complexes and their crystal packing arrangements have been established by X-ray crystallography. For complex 1, a tridentate hydrazone ligand (L1H) obtained by the condensation of benzhydrazide and 2-acetylpyridine is used, whereas a tridentate Schiff base (L2H) derived from benzoylacetone and 2-dimethylaminoethylamine is employed for the preparation of complex 2. Variable temperature magnetic susceptibility measurement studies indicate there are weak antiferromagnetic interactions with J values -0.10 and -1.41 cm-1 for 1 and 2, respectively. © 2007 Elsevier B.V.
