    Abstract: The polynuclear copper (Ⅱ) complex [Cu2 (Hdpa)2 (µ-ClDHBQ) (ClO4)2](subscript n), 1 is bridged by C1DHBQ^(-2) (2, 5-dichloro-3, 6-dihydroxy-1, 4-benzoquinone dianionic) and 2, 2'-dipyridylamine (Hdpa). In the axial position, Cu is connected with the oxygen atom of ClO4^(superscript -) The perchlorate anion may be envisaged as a monodentate O-bound ligand. Through the bond bridge of O-Cu…O-C1, the binuclear compound [Cu2 (Hdpa)2 (µ-C1DHBQ) (ClO4)2] is strung together into a long chain compound. Tetrachlorocatechol underwent partial oxidation/hydrolysis/dechlorination processes to produce C1DHBQ2. The other mononuclear complex [Cu (Hdpa) (TeCQ)] (DMF), 2, in which tetrachloroquinone (TeCQ) was produced by oxidation of tetrachlorocatechol (TeCC), therefore complex 2 is in the quinone form. The magnetic susceptibility measurements show antiferromagnetic coupling with J=-11.9cm^(-1), θ=2.6K, and g=2.05 for complex 1. Complex 2 exhibits the typical paramagnetic behavior of s=1/2.
