Compounds [Zn(2,2’-bipy)(L)Cl]2 1 and [Zn(phen)(L2)]2 2 (2,2’-bipy = 2,2’-bipy- ridine, HL = 3-methylbenzoic acid, phen = 1,10-phenanthroline) have been synthesized under hy- drothermal conditions. 1: monoclinic, space group C2/c, a = 20.240(4), b = 9.2960(19), c = 17.904(4) , β = 92.63(3)o, V = 3365.1(12) 3, C36H30Cl2N4O4Zn2, Mr = 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 C2/c, a = 23.035(5), b = 9.0395(18), c = 23.799(5) , β = 98.55(3)o, V = 4900.6(17) 3, C56H44N4O8Zn2, Mr = 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 > 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.
