温和条件原位配体反应合成铁四氮唑配合物及其晶体结构

Crystal Structure of An Ion Coordination Compound with Tetrazolyl Ligand Through In-situ Reaction under Mild Condition

利用2-氰基吡啶与叠氮阴离子,在开放体系、温和条件下发生Demko-Sharpless原位配体反应,合成得到铁四氮唑配合物[Fe(2-PTZ)2(H2O)2]。该配合物为单核结构,其晶体属单斜晶系,P21/c空间群。配合物通过分子间的氢键及错位的面对面π-π堆积作用形成三维超分子体系。

Using the Demko-Sharpless＇ method, a very effective method for tetrazole compound, a ion（Ⅱ） complex has been synthesized and structurally characterized, which was obtained under open system and mild condition by in-situ ligand reaction. The complex [Fe（2-PTZ）2（H2O）2] （1） crystallized in monoclinic, space group P21/c with a=0.810 4（2） nm, b = 1.288 0（3） nm, c =0.733 13 （18） nm,β=95.974（5） °, V=0.761 1 （3） nm^3, Z=2, and formed a 3D supramolecular networks through intermolecular hydrogen bond and off-set face-to-face π-π stacking.
