摘要
A new compound KFeNbOwas prepared for the first time by solid state reaction in KO FeO-NbOternary system. The X-ray powder diffraction data of the title compound was measured. KFeNbOcrystallizes in the hexagonal system with unit cell parameters a=9.1320(4)(?),c=12.0670(9)(?), and space group P63/mcm(193), z=1. The calculated and mea sured densities are 4.489 g/cm~3 and 4.485 g.cm~3, respec tively.
