Abstract:
Compounds [Zn(2, 2'-bipy)(L)Cl]2 1 and [Zn(phen)(L 2)]2 2 (2, 2'-bipy = 2, 2'-bipy- ridine, HL = 3-methylbenzoic acid, phen = 1, 10-phenanthroline) have been synthesized under hydrothermal conditions. 1: monoclinic, space group C2/c, a = 20.240(4), b = 9.2960(19), c = 17.904(4) Å, β = 92.63(3)°, V= 3365.1(12) Å3, C36H30Cl2N 4O4Zn2, MT = 784.32, Z = 4, Dc = 1.548 g/cm3, μ = 1.631 mm-1, F(000) = 1600, the final R= 0.0367 and wR = 0.1289 for 3867 observed reflections (I> 2σ(I)). 2: monoclinic, space group Cllc, a = 23.035(5), b = 9.0395(18), c = 23.799(5) Å, β = 98.55(3)°, V= 4900.6(17) Å3, C 56H44N4O8Zn2, M r = 1031.73, Z = 4, Dc = 1.398 g/cm3, μ = 1.039 mm-1, F(000) = 2128, the final R = 0.0540 and wR = 0.1287 for 5002 observed reflections (I> 2(7(7)). The two compounds have the same space group and similar isolated dinuclear structure, but different space packing structures are formed by different weak intermolecular interactions. Moreover, IR and luminescence spectra are also employed to study the crystal structures and properties of these two compounds.
