Abstract:
The two trinuclear nickel(II) complexes, Ni3(C 13H15N2O3)2(C 5H5N)4 (1) and Ni3(C 13H15N2O3)2(C 5H5N)2-(C3H7NO) 2 (2), were prepared by the reaction of Ni(OAc)2· 4H2O with N-hexanoylsalicylhydrazide. The crystal structures of complexes were determined by X-ray diffraction analysis. Complex 1 takes triclinic symmetry with space group P-1 and cell dimensions of a=0.92377(2) nm, b=1.08786(6) nm, c=1.29391(3) nm, α=76.395(4)°, β=78.418(3)°, γ=67.378(4)°, V=1.15772(7) nm3, Z=1, μ=12.63 cm -1. Complex 2 belongs to triclinic system and P2(1) space group and the crystallographic data: a=1.4889(2) nm, b=1.0389(1) nm, c=1.4994(2) nm, β= 96.174(4)°, V=2.3058(5) nm3, Z=2, μ=12.70 cm -1. The structures of the two molecules are similar. The three nickel atoms in each molecule of the two title complexes arrange in a strictly linear structure. The central nickel atom of the molecule adopts octahedral configuration, while the two nickel atoms on the two sides adopt square-planar configuration in each molecule. But the central nickel atoms of the two complexes have different axial ligands, which cause a slight difference in the bond distances of the octahedron. The antibacterial activity of compound 1 against seven common bacteria was investigated. © 2005 SIOC, CAS, & Wiley-VCH Verlag GmbH & Co. KGaA.
