摘要：

A cluster complex Cs3Nb2I9 is obtained by a high-temperature reaction of niobium, iodine, and cesium iodide. Its crystal structure is determined: trigonal space group P6(3)/mmc, a = 8.2463(3) , c = 19.5419(14) , V = 1150.84(10) (3), R(F) = 0.0614. The compound obtained is characterized by temperature independent paramagnetism in the temperature range 70-290 K.
