In this work, we prepared a three-dimensional vanadium octacya-noniobate- based magnet, K_0.10V^II_0.54^III _1.24[Nb^IV(CN)₈]·(SO₄) _0.45 6.8H₂O. This compound exhibits ferrimagnetism with a Curie temperature of 138 K, in which the sublattice magnetizations of V ^II (S = 3/2) and V^III (S = 1) are antiparallelly ordered to that of Nb^IV (S = 1/2). The estimated superexchange interaction constants of V^II-Nb^IV and V^III-Nb^IV are -51 and -25 cm^-1, respectively.
