| Abstract: A two-dimensional coordination polymer, [Cu(PAc)2(μ-3-PyOH)2]n(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) nm3, 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 two-dimensional 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.
