A Novel Zn(Ⅱ) Complex with 4-Connected umc Topology:Synthesis,Crystal Structure and Luminescent Property

A novel complex, [Zn(L)]2·H2O(1, H2 L = 4-aminophthalic acid), has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD. Complex 1 crystallizes in monoclinic, space group C2/c with a = 12.4267(6), b = 7.7482(3), c = 18.6983(8) ?, β = 110.437(3)o, V = 1687.04(13) ?3, Z = 4, C16H12N2O9Zn2, Mr = 507.06, Dc = 1.996 g/cm3, μ = 2.903 mm-1, S = 0.989, F(000) = 1016, the final R = 0.0304 and w R = 0.0720 for 12618 observed reflections(I 2σ(I)). Single-crystal X-ray structural analysis reveals that compound 1 features a three-dimensional(3D) framework with 4-connected umc topology. Moreover, the thermogravimetric(TG) analysis and photoluminescent property of 1 were also discussed.
