Abstract
Dipotassium trimolybdate, K2Mo3O10, crystallises in the monoclinic system, space group C2/c, with unit cell dimensions a= 13·902, b= 7·914, c= 8·845 Å, β= 98°50′. Its structure, determined by three-dimensional Patterson and Fourier syntheses and refined by least squares, contains distorted MoO6 octahedra and MoO5 square pyramids which share edges to form infinite chains parallel to the c axis. These chains are held together by potassium ions occupying irregular ten-co-ordinate interchain positions. The analogous trimolybdates, Rb2Mo3O10 and Cs2Mo3O10, have been shown to be isostructural and preliminary data for the previously unreported Ag2Mo3O10 is given.
