Ev. Murashova et Nn. Chudinova, SYNTHESIS AND CRYSTAL-STRUCTURE OF THE DOUBLE POLYPHOSPHATE RB2MN(PO3)(4), Inorganic materials, 34(10), 1998, pp. 1019-1023
The double polyphosphate Rb2Mn(PO3)(4) (monoclinic cell, sp. gr. P2(1)
/n, Z = 4; a = 7.810 Angstrom, b = 12.974 Angstrom, c = 11.302 Angstro
m, beta = 102.13 degrees) was synthesized in molten polyphosphoric aci
ds. This compound is isostructural with other M-2(+) M2+(PO3)(4) doubl
e polyphosphates.
