Abstract
A novel one-dimensional coordination polymer [Cu(μ 1,6-dmpzdo)(dmpzdo)2]·(ClO4)2 (dmpzdo = 2,5-dimethylpyrazine-1,4-dioxide) has been synthesized and its crystal structure determined by X-ray crystallography. In the complex each Cu1 atom is located in a square planar coordination environment with two oxygen atoms O2 and O2A from two dmpzdo terminal ligands, and two other oxygen atoms O3 and O3A from two μ 1,6-dmpzdo bridging ligands. The one-dimensional chain is constructed by the coordination of a μ 1,6-dmpzdo bridging ligand and Cu(II) ions. The data of the variable temperature (4–300 K) magnetic susceptibilities were fitted by using the one-dimensional chain fitting formula, which gave the magnetic coupling constants 2J = −98.88 cm−1.
