Abstract Two new polymorphs of ruthenium phosphate with RuP{sub 3}O{sub 9} composition were prepared and their crystal structures were determined by single-crystal X-ray diffraction. They are cyclo-hexaphosphate Ru{sub 2}P{sub 6}O{sub 18} and metaphosphate Ru(PO{sub 3}){sub 3}. Ru{sub 2}P{sub 6}O{sub 18} crystallizes in the monoclinic space group P2{sub 1}/c with a = 6.292(2) {angstrom}, b = 15.276(2) {angstrom}, c = 8.365(2) {angstrom}, {beta} = 106.54(2){degrees}, contains cyclo-hexaphosphate rings stacking obliquely along the [100] direction and is isotypic with B-form cyclo-phosphates. Ru(PO{sub 3}){sub 3} has a novel structure and crystallizes in the triclinic space group P1 with a = 6.957(1) {angstrom}, b = 10.324(2) {angstrom},c = 5.030(1) {angstrom}, {alpha} = 92.45(2){degrees}, {beta} = 92.31(2){degrees}, {gamma} = 98.61(1){degrees}, V = 356.5(1) {angstrom}{sup 3}, [PO{sub 3}{sup -}]{sub {infinity}} chains is different from that in the C-form Ru(PO{sub 3}){sub 3}. While the chains in the C-form consisting of PO{sub 3}-O-PO{sub 3} units are condensed in nearly staggered configurations, the units in the new phosphate are eclipsed.
