| dc.description | The crystal structures for T2[M(CN)6] where T = Mn, Cd; M = Fe, Ru, Os, were refined from the corresponding XRD powder patterns using the Rietveld method in the hexagonal P-3 (147) space group with Z = 1. In the structure of these families of anhydrous hexacyanometallates (II) the N end of the CN group appears bifurcated, serving as a ligand for two neighbouring T metals. Such a coordination mode has not been reported before for transition metal hexacyanometallates but it is consistent with the magnetic properties and M¨ossbauer, IR and Raman spectra of the studied compounds. The anhydrous solids are obtained by dehydration of the corresponding octahydrates. In the hydrated form the metals (Mn, Cd) linked at the N ends have a mixed coordination sphere formed by three N atoms and three coordinated waters, with two of these latter forming bridges between two neighbouring metals. The loss of these structural waters leaves the metals (T ) in an unstable state with only three ligands in their coordination sphere and a structural transformation involving a change in the CN group electronic configuration is induced. The metal coordination through bifurcated CN groups leads to a remarkable increase in the charge overlapping between the metal centres, which appears attractive for molecular magnet design. | - |
