Abstract :The magnetic properties and redetermination of crystal structure of copperinsert ignore into journalissuearticles values(II); acetate monohydrate have been studied. The copperinsert ignore into journalissuearticles values(II); centers are separated by 2.617insert ignore into journalissuearticles values(1); \AA \ and antiferromagnetically coupled insert ignore into journalissuearticles values(-2J = 292.2 cm-1);, which follows from temperature-dependent magnetic susceptibility measurements in the temperature range 4.2 to 300 K. The magnetic moment at 300 K is about 2.1 Bohr magnetons while 0.1 Bohr magnetons at 4.2 K. The magnetic susceptibility is at a maximum near 250 K and decreases rapidly as the temperature is lowered to liquid helium temperature.
