Abstract
Two dinuclear complexes [Zn(m-L)(NO3)(H2O)]2 (1) and [Cu2(m-L)2(HL)2](NO3)2(C12H8Br2)0.5××H2O (2), (HL = 3-(2-pyridyl)pyrazole, C12H8Br2 = 4,4¢-dibromobiphenyl) are synthesized under hydrothermal conditions and characterized by elemental analysis and X-ray single crystal diffraction. Crystal data for 1: triclinic, P , a = 8.8478(7) Å, b = 15.0550(11) Å, c = 16.4310(12) Å, a = 107.588(4)°, b = 112.498(3)°, g = 115.595(3)°, V = 2099.8(9) Å3, Z = 2; for 2: triclinic, P , a = 7.2870(15) Å, b = 8.6840(17) Å, c = 9.3290(19) Å, a = 107.588(4)°, b = 112.498(3)°, g = 115.595(3)°, V = 528.77(18) Å3, Z = 1. Complex 1 and 2 are both dinuclear structures which are further packed into a 1D supramolecular chain and a 3D supramolecular framework via weak C-H⋯O hydrogen bond interactions respectively.
