合成了Schiff碱N 氧化吡啶 2 甲醛缩氨基脲 (PNOS)及其配合物 [Cu(PNOS) (NO3 ) 2 ],并用单晶X射线衍射法测定了配体和配合物结构 .PNOS晶体中通过传统氢键形成双层二维网状结构 ,再由非传统氢键自组装成三维网状结构 .配合物 [Cu(PNOS) (NO3 ) 2 ]中的铜为六配位 ,畸变八面体结构 ,Schiff碱 (PNOS)通过N 氧化吡啶N—O的O原子 ,亚胺基CN的N原子 ,及羰基CO的O原子与铜配位 ;一个硝基以单齿配体形式与铜配位 ,另一个则以双齿配体形式配位 .配合物分子通过经典氢键相互作用 ,形成单层二维网状结构 ,再通过非经典氢键作用 ,自组装成双层二维网状结构
Schiff base PNIN and its complex [Cu (PNOS) (NO3) 2] were synthesized and their structures were determined by single crystal X-ray diffraction Traditional hydrogen bonds form a two-dimensional two-dimensional network structure, which is self-assembled into a three-dimensional network structure by non-traditional hydrogen bonds. The copper in the complex [Cu (PNOS) (NO3) 2] is a hexacoordinated, distorted octahedral structure , Schiff base (PNOS) is coordinated with copper via the O atom of N-O N oxide, N atom of imine CN and O atom of carbonyl CO. One nitro group coordinates with copper as monodentate ligand, The other is coordinated by bidentate ligands.The complex molecules through the classical hydrogen bonding interaction, forming a two-dimensional network structure of single layer, and then through non-classical hydrogen bonding, self-assembled into two-dimensional two-dimensional network structure
