It was crystallized in a monoclinic system, space group P2(1)/n, with a = 8.0297(8) , b = 12.4937(14) , c = 15.3786(15) , beta = 102.739(8) and z = 2. Each copper(II) has a square-based pyramidal coordination geometry with four N atoms building the basal plane (three from dien and one from mu-1,6-DAH). TGA study of the complex revealed the compound to be stable up to 245 A degrees C. Electrochemical behavior of complex and enzyme-like catalytic activity of this complex, as a potential functional model for the active site of tyrosinase, was studied extensively. Kinetic studies show that the complex has the maximum enzymatic activity at pH 8, temperature of 40 A degrees C and ionic strength of 50 mM.
