摘要
A novel heterospin complex {[(CuL)Ni(IM 2Py) 2](ClO 4) 2} 2·2H 2O (L=2,3 dioxo 5,6:14,15 dibenzo 1,4,8,12 tetraazacyclo pentadeca 7,12 diene, IM 2Py=2 (2′ pyridyl) 4,4,5,5 tetra^methyl 4,5 dihydro 1 H imidazoline 1 oxyl) has been synthesized and its crystal structure was determined by X ray diffraction analysis. In order to interpret the exchange interaction of this asymmetric heterospin system, a theoretical model has been established. Using this theoretical model the magnetic susceptibility data have been fitted and lead to coupling constant values equal to 1 4 cm -1 (Ni Rad) and -38 0 cm -1 (Ni Cu), respectively.
