摘  要:羟基吡啶不仅是一类有机和药物合成的重要中间体,而且它含有的氮和氧两种配位原子,被认为是一种潜在的构筑配位聚合物的组织基元,近年来在晶体工程学和超分子化学领域中引起极大的重视。目前,对以羟基吡啶为小分子桥联配体参与构建一维或多维配位聚合物的研究主要集中在邻-羟基吡啶及其共振衍生物,而对于3-羟基吡啶及其配合物的研究报道很少,特别是以3-羟基吡啶作为配体构筑的铜(Ⅱ)配合物的结构研究报道很少。A two-dimensional coordination polymer, [Cu(PAc)2(μ-3-PyOH)2], (HPAc=phenyl acetic acid, 3-PyOH= 3-hydroxypyridine) was synthesized and characterized by the element analysis, IR, TG and X-ray diffraction single crystal structure determination. The title complex crystallizes in the monoclinic system with space group P21/c, a=1.228 7(3) nm, b=0.967 05(19) nm, c=1.076 4(2) nm,β=109.93(3)° and V=1.202 4(5) nm^3, Z=2, Mr= 524.01, F(000)=542,μ=0.953 mm^-1, R=0.030 9, wR=0.080 7. Each copper(Ⅱ) ion displays an elongated octahedron with two nitrogen atoms from two different 3-PyOH ligands and two oxygen atoms from two different terminal phenyl acetate groups occupying the basal positions and two oxygen atoms of two different 3-PyOH ligands from the neighbouring molecules occupying the axial positions. Each four identical mononuclear Cu(Ⅱ) unit in the twodimensional layer is joined by four 3-PyOH ligands, related by inversion centers with a Cu…Cu separation of 0.723 5(10) nm across the 3-PyOH-N,O bridge in bc plane.
