In the title coordination polymer, Zn(C(7)H(6)NO(2))(2)(H(2)O)(2), the Zn(II) cation is located on an inversion center and is coordinated by four pyridyl-acetate anions and two water mol-ecules in a distorted ZnN(2)O(4) octa-hedral geometry. The pyridine-N and carboxyl-ate-O atoms of the pyridyl-acetate anion connect to two Zn(II) cations, forming a two-dimensional polymeric complex extending parallel to (212). Inter-molecular O-H⋯O and weak C-H⋯O hydrogen bonding is present in the crystal structure.
在标题配位聚合物[Zn(C₇H₆NO₂)₂(H₂O)₂]ₙ中,Zn(II)阳离子位于一个对称中心上,在扭曲的ZnN₂O₄八面体几何构型中由四个吡啶基乙酸根阴离子和两个水分子配位。吡啶基乙酸根阴离子的吡啶-N和羧酸根-O原子连接到两个Zn(II)阳离子上,形成一个平行于(212)延伸的二维聚合物配合物。晶体结构中存在分子间O-H⋯O和弱C-H⋯O氢键。
