Synthesis, Crystal Structure and Theoretical Calculation of a Novel 2D Network of Manganese(Ⅱ) Complex
【摘要】 A novel complex, [Mn(2-NCP)(H2BTC)(H2O)]n(1, 1,3,5-H3BTC = 1,3,5-benzenetricarboxylic acid, 2-HNCP = 2-(2-carboxyphenyl)-1 H-imidazo(4,5-f)-(1,10)phenanthroline), was hydrothermally synthesized and structurally characterized by elemental analysis, IR, XRD and single-crystal X-ray diffraction. Structural analyses reveal that complex 1 exhibits a(6, 6)-connected topology network with a Schl?fli symbol of(63). The adjacent 2 D layers are further stacked via strong hydrogen-bonding interactions, giving a 3 D supramolecular framework. In addition, the structure of complex 1 was calculated by the B3LYP/LANL2 DZ method by Gaussian program. The results from natural bond orbital(NBO) analysis shows obvious covalent interaction between the coordinated atoms and Mn(Ⅱ) ion.
