Synthesis, structures, luminescence/magnetic properties of complexes of the M/1-hydroxybenzotriazole, M = cobalt, nickel, silver, zinc and copper

摘要

Five novel complexes, Co(0Bt)_2 _7H_2O (1) (OBt= 1-hydroxybenzotriazole ion), Ni_3(0Bt)_6.6H_20 (2), [Ag(OBt)(HOBt)]_n (3), [Zn(0Bt)_2]_n (4) and [Cu_2(0Bt)_4 3H_2O1_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 (OD), zero-dimensional, one-dimensional (ID), 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_12_12_1 with a helical chain in its structure. The luminescence properties and the magnetic properties of the five complexes were investigated.
