Molecule-based magnets formed by bimetallic three-dimensional oxalate networks and chiral Tris(bipyridyl) complex cations. the series [Z(sup)II(bpy)(sub)3][CIO(sub)4][M(sup)IICr(sup)III(ox)(sub)3] (Z(sub)II = Ru, Fe, Co, and Ni; M(sub)II = Mn, Fe, Co, Ni, Cu, and Zn; ox = oxalate dianion)

Research demonstrates the synthetic, structural, and magnetic properties of oxalato-bridged bimetallic magnets. Data show that the compounds are isostructural with cubic space group made of three-dimensional bimetallic network of M(sup)II and chromium(sup)III ions which in turn bridged by oxalateanions.
