Abstract: In this paper, a copper complex by using 2,2’-bipyridine -5,5’- dicarboxylic acid, copper oxide and perchloric acid through hydrothermal method are obtained. X-ray diffraction and SHELXTL software was used to analyze the structure of the complex Cu(H₂bpdc)·ClO₄(1) and the result shows that the complex 1 is a zero-dimensional structure. In complex 1, there are many hydrogen bonds between molecules, which results in a three-dimensional network structure through hydrogen bonds and π-π interaction. The solid fluorescence studies have shown that the phenomenon of fluorescence is quenching after the ligand coordination with the Cu^II ion. Thermo gravimetric analysis is used to study the thermal stability of the complex 1 and the relationship between thermal decomposition and the crystal structure. The research provides guidance and reference for exploiting new multi-dimensional organic metal frame structures and fluorescent materials.
