We report a cyano-bridged VNb bimetal assembly, K0.59VII1.59VIII0.41[NbIV(CN)8]center dot(SO4)(0.50)center dot 6.9H2O, exhibiting ferrimagnetism with a high Curie temperature (TC) of 210 K, which is the highest TC value among those of octacyano-bridged bimetal assemblies. Such a high TC value originates from the high coordination number of octacyanoniobate and the strong superexchange interaction between VII (S = 3/2) and NbIV (S = 1/2) through the CN groups.
