Crystals of RbPrHP{sub 3}O{sub 10} have been grown by the flux technique and characterized by single-crystal X-ray diffraction. RbPrHP{sub 3}O{sub 10} crystallizes in the triclinic P1-bar space group with lattice parameters: a=7.0655(5), b=7.7791(4), c=8.6828(6) A, {alpha}=74.074(3), {beta}=74.270(3), {gamma}=82.865(2){sup o}, V=441.09(5) A{sup 3}, Z=2. The crystal structure has been solved yielding a final R(F{sup 2})=0.0443 and R{sub w}(F{sup 2})=0.1426 for 1955 independent reflections (F{sub o}{sup 2}>=2{sigma}(F{sub o}{sup 2})). The structure of RbPrHP{sub 3}O{sub 10} consists of PrO{sub 8} polyhedra and P{sub 3}O{sub 10}{sup 5-} groups sharing oxygen atoms to form a two-dimensional framework; the PrO{sub 8} polyhedra form infinite chains by edge-sharing. Each Rb{sup +} ion is bonded to 10 oxygen atoms, these ions are located between chains formed of (HP{sub 3}O{sub 10}){sup 4-}. The energies of the vibrational modes of the crystal were obtained from measurements of the infrared spectrum.
