Synthesis and structure of 1-D heterometallic thiocyanato-bridged CuIIGdIII polymers with ferromagnetic properties

Reaction of the tetracoordinate CuLA and CuLB complexes with Gd(NCS)(3) leads to two unique one-dimensional {Cu-Gd}(n) thiocyanato-bridged (1) and hydrogen-bonded (11) polymers, depending on the periphery of the L-A and L-B ligands, with ferromagnetic properties.
