چکیده
The title compound, [Zn(C(8)H(4)O(4))(C(5)H(8)N(2))(3)], has a neutral monomeric structure in which one terephthalate dianion and three 2-ethyl-1H-imidazole ligands coordinate to the Zn(II) ion in a distorted tetra-hedral geometry. The methyl group of one of the ethyl groups is disordered over two positions with occupancies of 0.66 (2) and 0.34 (2). In the crystal structure, mol-ecules are linked into a three-dimensional hydrogen-bonded network by inter-molecular N-H⋯O interactions involving the uncoordinated carboxyl-ate O atoms.

The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely d...
