摘 要: | Compounds [Zn(2,2'-bipy)(L)Cl]2 1 and [Zn(phen)(L2)]2 2 (2,2'-bipy = 2,2'-bipyridine, 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)A, β = 92.63(3)°, V = 3365.1(12) A^3, C36H30Cl2N4O4Zn2, Mr = 784.32, Z = 4, Dc = 1.548 g/cm^3, 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 C2/c, a = 23.035(5), b = 9.0395(18), c = 23.799(5) A, β = 98.55(3)°, V = 4900.6(17)A^3, C56H44N4O8Zn2, Mr = 1031.73, Z = 4, Dc = 1.398 g/cm^3, μ = 1.039 mm^-1, F(000) = 2128, the final R = 0.0540 and wR = 0.1287 for 5002 observed reflections (I 〉 2σ(I)). 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. Mo- reover, IR and luminescence spectra are also employed to study the crystal structures and pro- perties of these two compounds.
