چکیده
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.
