Magnetic study of a cyano-bridged bimetallic complex with Cu2+ macrocycle and [Fe(CN)6]3− ions as building blocks
摘要:
A new bimetallic cyano-bridged complex, based on copper(II) macrocycle and hexacyanoiron(III) as building blocks, [CuL(H2O)(2)]{[CuL][Fe(CN)(6)] center dot 2H(2)O} (1) (L = 1,3,6,8,11,14-hexaazatricyclo[12.2.1.18,11]-octadecane) has been synthesized and magnetically characterized. Make a study of magnetic using a chain model which takes into account of monomeric impurity confirm showing an antiferromagnetic coupling in paramagnetic ions with J = -0.170 cm(-1) and 3.56 % impurity.
