The reaction of Zn(NO(3))(2) with pyridine-2,6-dicarboxylic acid (pydcH(2)) and acridine (acr) in aqueous solution leads to the formation of the title compound, (C(13)H(10)N)[Zn(C(7)H(3)NO(4))(C(7)H(4)NO(4))]·5H(2)O or (acrH)[Zn(pydcH)(pydc)]·5H(2)O. In the title compound, the Zn(II) atom is coordinated by four O atoms and two N atoms from the tridentate chelating rings of (pydc)(2-) and (pydcH)(-) anions. The geometry of the resulting ZnN(2)O(4) coordination can be described as distorted octa-hedral. To balance the charges, one protonated acridine (acrH)(+) cation is present. In the crystal structure, extensive O-H⋯O and N-H⋯O hydrogen bonds involving acrH(+), the complex anion and uncoordinated water mol-ecules form a three-dimensional network.
硝酸锌（Zn(NO₃)₂）与吡啶 - 2,6 - 二羧酸（pydcH₂）及吖啶（acr）在水溶液中反应生成标题化合物，即（C₁₃H₁₀N）[Zn(C₇H₃NO₄)(C₇H₄NO₄)]·5H₂O 或（acrH）[Zn(pydcH)(pydc)]·5H₂O。在标题化合物中，Zn(II) 原子由来自（pydc）²⁻ 和（pydcH）⁻ 阴离子的三齿螯合环中的四个 O 原子和两个 N 原子配位。所得 ZnN₂O₄ 配位的几何形状可描述为扭曲八面体。为平衡电荷，存在一个质子化的吖啶（acrH）⁺ 阳离子。在晶体结构中，涉及 acrH⁺、络合阴离子和未配位水分子的广泛 O - H⋯O 和 N - H⋯O 氢键形成三维网络。
