Abstract

Methods of chemical preparation and crystal data are reported for four new condensed phosphates: two hydrated cyclotriphosphates with a general formula SrMIP3O9⋅3H2O (MI=K+,Tl+) and their corresponding anhydrous cyclotriphosphates SrMIP3O9 (MI=K+,Tl+). The two hydrated condensed phosphates, SrKP3O9⋅3H2O and SrTlP3O9⋅3H2O, belong to previously investigated structure types. SrKP3O9⋅3H2O and SrTlP3O9⋅3H2O are orthorhombic, Z=4, space group Pnma, with respectively the following unit-cell dimensions: a=9.082(2) Å, b=8.133(2) Å, c=15.009(2) Å, M(20)=49, F(25)=61(0.0052;79) and a=9.115(7) Å, b=8.139(7) Å, c=15.221(2) Å, M(20)=285, F(30)=522(0.000 411;140). SrKP3O9 and SrTlP3O9 are monoclinic, space group P21/m or P21, Z=4, with, respectively, the following unit-cell dimensions: a=14.957(1) Å, b=8.372(1) Å, c=7.909(1) Å, β=102.27(1)°, M(20)=81, F(24)=95(0.000 025;92) and a=14.544(2) Å, b=8.639(1) Å, c=7.727(1) Å, β=102.05(1)°, M(20)=66, F(30)=78(0.003 098;125).
