摘要
Co(II) and Zn(II) complexes based on 1-(5-tetrazolyl)-4-(1-imidazolyl)benzene (HL) and 1,4-benzenedicarboxylic acid (H(2)pbda): [Co-2(L)(2)(pbda)(H2O)(3)] (1) and [Zn(L)(pbda)(0.5)] (2) have been prepared under hydrothermal conditions and characterized by single crystal and powder X-ray diffractions. IR, and thermogravimetric analysis. Complex 1 exhibits binodal (3.5)-connected 2D net structure with (3.5(2))(3(2).5(3).6(4).7) topology; while 2 is a binodal (3,4)-connected 2-fold interpenetrating 3D framework with dmc (4.8(2))(4.8(5)) topology. The influence of coordination geometries of metal centers on the structures of resultant complexes is discussed. Moreover, magnetic property of 1 and luminescence of 2 were investigated.
