Structure and magnetism of the first cyano-bridged hetero-one-dimensional Gd-III-Cr-III complexes

A reaction between Gd(NO3)(3). 6H(2)O, K-3[Cr(CN)(6)] and dmf or bpy has allowed the synthesis of two new ferrimagnetic Gd-III-Cr-III chains which are the first low-dimensional 4f-Cr-III systems; magnetic susceptibilty data indicate antiferromagnetic coupling between Gd-III and Cr-III.
