摘要
水热条件下,合成了配位聚合物[Zn(L)2(H2O)](nLH=2-吡啶-2-苯并咪唑).X-射线单晶衍射分析结果表明:配合物属单斜晶系,P2(1)/c空间群,晶胞参数分别为:a=12.5657(2),b=12.9258(2),c=13.2403(3)A°,β=102.738(1)A°.锌离子与两个LH的4个氮原子,1个端基水配位形成变形的四角锥,(I)通过O---H---N氢键形成一维超分子结构.
The title compound[Zn(L)2(H2O)]n,(I),(where LH=2-Pyridin-2-yl-1H-benzoimidazole),was synthesized by hydrothermal reactions.X-ray single-crystal analyses were carried out for(I), which crystallizes in the Monoclinic system,space group P2(1)/c, with a=12.5657(2) ,b=12.9258(2) ,c=13.2403(3) ,β=102.738(1),and Z=4.The single X-ray diffraction studies reveal that the Zn(II) atom is coordinated a distorted tetragonal pyramid by four nitrogen atoms from two L-and one aqua ligand. (I) constructs a one dimensional supramolecular network through the O-H-N hydrogen bonds.
