摘要:
A new zinc(II) complex Zn(H(3)Pimda)(2)] center dot H2O (I), where H(3)Pimda = 2-Propyl-1H-imidazole-4, 5-dicarboxylic acid, has been synthesized and characterized by elemental analysis, IR spectroscopy and X-ray single-crystal diffraction. It crystallizes in the triclinic system, space group P1 , with a = 8.397(3), b = 11.271(4), c = 12.312(5), alpha = 70.432(5), beta = 70.984(5), gamma = 74.897(5)A degrees, V = 1022.9(7) (3), M (r) = 475.71, Z = 2, rho (c) = 1.695 g/cm(3), F(000) = 488, mu = 1.151 mm(-1), R = 0.0659 and Rw =0.1525 for 3769 observed reflections. The hydrogen bonding derived from the coordinated waters connects the mononuclear zinc complex units into a one-dimensional chain, and these chains are further linked by intermolecular hydrogen bonds into a 2D supramolecular network. Complex I also displays strong photoluminescence properties in the liquid state at room temperature.
