| Abstract: | Two new coordination complexes Co(1,2,4-HBTC)(tib)] (1) and Ni4(1,2,4-BTC)2(tib)4(H2O)j ·(1,2,4-HBTC) ·9H20 (2) (1,2,4-H3BTC=l,2,4-benzenetricarboxylic acid, tib=l,3,5-tris(1-imidazolyl)benzene) were obtained by hydrothermal reactions of 1,2,4-H3BTC and tib with corresponding metal salts. Single crystal X-ray diffraction analysis revealed that each tib ligands connect three metal atoms to form two-dimensional (2D) networks in 1 and 2. On the other hand, each 1,2,4-HBTC2- coordinates to one Co(Ⅱ) atom as a terminal ligand in 1, while in 2, two 1,2,4-BTC3- ligands link four Ni(Ⅱ) atoms which further connect Ni(tib)]2+ 2D networks to result in formation of multi-layered 2D structure. Complexes 1 and 2 are finally extended to three-dimensional (3D) supramolecular structures by hydrogen bonding interactions. |
