Jl. Prisset et al., THE PB(PO3)2-RBPO3 PHASE-EQUILIBRIUM DIAGRAM CRYSTAL-STRUCTURE OF PBRB(PO3)3, European journal of solid state and inorganic chemistry, 31(1), 1994, pp. 37-46
The Pb(PO3)2-RbPO3 phase-equilibrium diagram has been established by D
TA. PbRb(PO3)3, the only intermediate compound observed in this system
, is a long-chain polyphosphate. This salt is monoclinic, P2(1)/n, wit
h Z = 8 and the following unit-cell dimensions : a = 14.05(3), b = 17.
09(4), c = 7.228(3) angstrom, beta = 103.85(5)-degrees The atomic arra
ngement is mainly characterized by infinite (PO3)n chains running alon
g the b direction with a period of twelve tetrahedra.
