The crystal structure of La5Mo6O21 (pentalanthanum hexamolybdenum henicosaoxide) is made up of Mo3O13 units containing triangular {MoIV}3 clusters, three distorted MoVO6 octahedral units and six interstitial LaIII atoms. The Mo3O13 unit consists of three edge-sharing MoIVO6 units involving Mo-Mo bonding. The three MoVO6 octahedra share their corners or edges with each other and with the Mo3O13 units.
