“…A comparison of the Debye pattern with calculated spacings of the LiPO 3 structure of Guitel & Tordjman (1976) shows that these authors analyzed the high-temperature crystal form (see Table I, 22 reflexions, average error"-0.002, standard deviation +0.014 /k) {monoclinic, a ---16.453, b = 5.405, c = 13.086 A, fl= 98.99 °, Z = 20, density --2.482 Mg m-a; chain axis along [10il with a five-PO~-tetrahedra repeat length of 9.678 /k}. The average P-P distance of adjacent PO~-tetrahedra within the chain is 2.94 A.…”
