Magnetic properties of two 2D complexes based on 1D chain containing [Fe(bpy)(CN)4] unit

Abstract

Two heterobimetallic 2-dimensional layer complexes, {[Fe(bpy)(CN)4]2M(4,4′-bipyridine)}·4H2O [bpy = 2,2′-bipyridine, M = Mn (1), Cu (2)] have been prepared by diffusion and their structures determined by single crystal X-ray diffraction. 1 and 2 are isomorphous, made of neutral bimetallic [Fe(bpy)(CN)4]2M(4,4′-bipyridine)] layers and uncoordinated water molecules located between the layers. Interestingly, complex 2 shows the compression of the Jahn–Teller distortion around the copper(II) ion. Magnetic investigation shows antiferromagnetic coupling between the manganese(II) and iron(III) ions mediated by bridging CN in 1, while ferromagnetic coupling between the copper(II) and iron(III) ions is seen in 2. Both complexes 1 and 2 reveal a metamagnetic-like behaviour with different critical fields (Hc, at 1.8 K): 2.0 kOe (1) and 3.2 kOe (2). The weak interchain antiferromagnetic interaction can be illustrated by the spin-polarization mechanism.
