T A Schiff base ligand(H2CSF,C13H11NO4,1)derived from 3-carboxylsalicylaldehyde and furfurylamine,and its trinuclear complex[Ni3(CSF)2(CH3COO)2(DMF)2(H2O)2](2)were synthesized.Compound 1 was characterized by elemental analysis,1 H NMR,IR,MS and X-ray diffraction analysis.The crystal of 1 belongs to the monoclinic system,space group P21/c with α=8.472(2),b=19.743(5),c=7.2300(18)(A),β=110.278(4)°,V=1134.4(5)(A)3,Z=4,Mr=245.23,Dc=1.436 g.cm-3,μ=0.108 mm-1,F(000)=512,λ=0.71073(A),the final R=0.0440 and wR=0.1199 for 1426 observed reflections(Ⅰ＞2σ(Ⅰ)).In the crystal of 1,there exist intramolecular characterized by elemental analysis,IR,TG and X-ray diffraction analysis.The crystal of 2 is of triclinic system,space group P-1 with a=10.1237(17),b=10.4086(18),c=10.4884(18)(A),α=μ=1.463 mm-1,F(000)=498,λ=0.71073(A),the final R=0.0517 and wR=0.0805 for 2065observed reflections(Ⅰ＞20(Ⅰ)).The geometry of the trinuclear molecule is centrosymmetric,in which every Ni(Ⅱ)ion is coordinated in a slightly distorted octahedron.The three Ni(Ⅱ)ions are arranged in a straight line.The two CSF2-ions act as NOO tridentate ligands with the phenolate and carboxylate oxygen as bridging atoms.The coordination atoms of CSF2-anions and water molecules are coordinated on the equatorial plane,while the two bridging acetate ions and two DMF are tram-coordinated on the apical sites.
