Cu(Ⅱ)与N-(2-羟苄基)-DL-丙氨酸、4,4′-联吡啶三元配合物的合成与晶体结构

Synthesis and Crystal Structure of Ternary Copper(Ⅱ) Complex Containing N-(2-hydroxybenzyl)-DL-alanine and 4,4′-bipyridine

近年来，基于金属和有机配体间的配位键合作用来设计和构筑具有多孔结构的超分子体系已成为现代化学、材料科学领域内非常活跃和充满前景的研究主题之一。为实现这目标，探求决定配合物配位几何构型的因素及通过配体的设计来控制配合物的结构已引起化学家们广泛的兴趣。

A supramolecular compound [Cu（sala）（4,4＇-bipy）2]-0.5（4,4＇-bipy）＇2H2O （sala=N-（2-hydroxybenzyl）-DL-alaninate, 4,4＇-bipy=4,4＇-bipyridine） was synthesized and characterized by elemental analysis, IR, and the crystal structure was determined by X-ray diffraction technique. It crystallizes in orthorhombic system with space group Pbca. The crystal data are： a/=1.8777（3） nm, b=1.6367（2） nm, c=2.149 8（2） nm, and V=6.6069（10）nm^3, Z=8, Dc= 1.374 g·cm^-3, /z=0.713 mm^-1, F（000）=2 848, R1=0.044 6, wR2=0.105 7. In the title complex, Cu（Ⅱ） ion is five coordinated with distorted square pyramid configuration. The complex formed three-dimensional porous supermolecular structure through or-or stacking and hydrogen bonds. There exist uncoordinated 4,4＇-bipy molecules in the compound, exhibiting a certain inclusion phenomenon. CCDC： 648620.
