In the title complex, {[Zn(C(7)H(3)NO(4))(C(12)H(8)N(2))]·H(2)O}(n), the Zn(II) ion is in a distorted octa-hedral environment, defined by two N atoms from a chelating 1,10-phenanthroline (phen) ligand and one N atom and three O atoms from two pyridine-2,3-dicarboxyl-ate (2,3-pydc) ligands. The bridging 2,3-pydc ligands connect the Zn(II) ions into a chain extending along [010]. O-H⋯O hydrogen bonds between the uncoordinated water mol-ecules and the uncoordinated carboxyl-ate O atoms, as well as π-π inter-actions between the pyridine rings of the phen ligands [centroid-centroid distance = 3.557 (2) Å], are observed.
在标题配合物{[Zn(C₇H₃NO₄)(C₁₂H₈N₂)]·H₂O}ₙ中,Zn(II)离子处于扭曲的八面体环境中,由来自螯合的1,10 - 菲咯啉(phen)配体的两个N原子以及来自两个吡啶 - 2,3 - 二羧酸酯(2,3 - pydc)配体的一个N原子和三个O原子界定。桥连的2,3 - pydc配体将Zn(II)离子连接成沿[010]方向延伸的链。观察到未配位水分子与未配位羧酸根O原子之间的O - H⋯O氢键,以及phen配体吡啶环之间的π - π相互作用[质心 - 质心距离 = 3.557 (2) Å]。
