摘要:
Five novel complexes, Co(OBt)(2) center dot 7H(2)O (1) (OBt = 1-hydroxybenzotriazole ion), Ni-3(OBt)(6) center dot 6H(2)O (2), [Ag(OBt)(HOBt)](n) (3), [Zn(OBt)(2)](n) (4) and [Cu-2(OBt)(4) center dot 3H(2)O](n) (5) were synthesized by hydrothermal method and characterized by elemental analysis, IR spectroscopy, TGA, XRPD, and single-crystal X-ray diffraction. The results from single-crystal X-ray diffraction indicate that 1-5 are zero-dimensional (0D), zero-dimensional, one-dimensional (1D), and three-dimensional (3D) frameworks, respectively. In particular, 3 is twin crystal; 4 possesses of double-stranded chains; 5 crystallizes in orthorhombic space group P2(1)2(1)2(1) with a helical chain in its structure. The luminescence properties and the magnetic properties of the five complexes were investigated. (C) 2009 Elsevier B.V. All rights reserved.
