Metal organic complexes is currently a hot research frontier, assembled by the design of novel organic ligand with metal ions complexes of organic ligands and inorganic metal ions on the structure of the complexes as well as the nature of the complexes, mainly to obtain the following results: 1. designed in this paper synthesized novel bidentate, tridentate organic ligands, including five kinds of rigid ligand, L 6 is not as rigid ligands, L 1 , L 2 is a multi-carboxylic acid ligands, using the oxygen atom of the carboxylate with a metal ion ligand, and L 3 , L 4 , L 5 and L 6 imidazole or pyridine nitrogen atoms and the metal ion coordination. The configuration formed by self-assembled with the copper ion, zinc ion, cadmium ion, silver ion, cobalt ion and nickel ion 11 kinds Exotic crystals, are tabulated below. Among them, there is a one-dimensional chain structure, such as 5 and 6 complexes; two-dimensional mesh structure, such as the complexes 1,2,3,8 and 9; three-dimensional network structure, such as the complexes of 4,7 and 8. Another complexes 1 and 2 double interspersed structure complexes 7 and 8, compared with the quintet interspersed structure.
