| In recent years, much attention has been paid on the design, synthesis, crystal structures and properties of the carboxylate complexs, as the carboxylate coordination complexs have fascinating topological structures and various applications in the areas of biology, catalysis, optical and maganetic materials. The design and synthesis of materials with novel structures are topics of current interest and of great challenge. At present, the most chosen carboxylate ligands are rigid aromatic carboxylate.In the thesis, the flexible cyclohexanecarboxylate has been researched. The cyclohexanecarboxylate acts as the main ligand, while 2,2'-bpy and 4,4'-bpy as the second ligands. Five metal complexs are obtained. A novel cobalt quinine complex and two tetrazol complexs have been synthesized. They have been characterized by FT-IR, elemental analysis, XRD and single-crystal X-ray crystallography. The main contents in this thesis are as follows:1. Complex [Mn2(C6H11CO2)3(4,4'-bipy)2(H2O)2]ClO4(1) (C6H11CO2H= yclohexanecarboxylic acid) was synthesized by reaction of Mn(ClO4)2·6H2O,C6H11CO2Na and 4,4'-bipy in methanol. The title complex crystallized in triclinic space group P1, with a=1.0088(2), b =1.0863(1), c=1.1649(3) ran,α=63.016(3),β=81.998(4),γ= 88.604(1)?, V=1.1254(4) nm3, Z=1. There are two types of Mn atoms in the structure with each in octahedral geometry. Mn1 and Mn2 are bridged by cyclohexanecarboxylate ligands into a chain and the chains are further linked together by 4,4'-bipy into a 2-D plane.2.
