Hydro-thermal reaction involving zinc nitrate hexa-hydrate, tris-odium benzene-1,3,5-tricarboxyl-ate (Na(3)BTC) and 2-methyl-imidazole (2-MeImH) yielded the title compound, [Zn(2)(C(9)H(3)O(6))(C(4)H(5)N(2))(C(4)H(6)N(2))(3)]. In this mixed-ligand metal-organic compound, Zn(2+) ions are coordinated by N atoms from 2-MeImH mol-ecules and (2-MeIm)(-) ions, as well as by O atoms from (BTC)(3-) ions. This results in two different distorted tetra-hedra, viz. ZnN(3)O and ZnN(2)O(2). These tetra-hedra are inter-connected via (BTC)(3-) ions and N:N'-bridging (2-MeIm)(-) ions, thus forming a layered structure in the bc plane. Hydrogen bonds between the O atoms of carboxyl-ate ions and NH groups of 2-MeImH ligands link the layers into a three-dimensional structure.
涉及六水合硝酸锌、苯 - 1,3,5 - 三羧酸钠（Na₃BTC）和2 - 甲基咪唑（2 - MeImH）的水热反应生成了标题化合物[Zn₂(C₉H₃O₆)(C₄H₅N₂)(C₄H₆N₂)₃]。在这种混合配体金属有机化合物中，Zn²⁺离子由2 - MeImH分子和(2 - MeIm)⁻离子中的N原子以及(BTC)³⁻离子中的O原子配位。这导致形成两种不同的扭曲四面体，即ZnN₃O和ZnN₂O₂。这些四面体通过(BTC)³⁻离子和N:N' - 桥连的(2 - MeIm)⁻离子相互连接，从而在bc平面上形成层状结构。羧酸根离子的O原子与2 - MeImH配体的NH基团之间的氢键将这些层连接成三维结构。
