<jats:p>Methods of chemical preparation and XRD data are reported for a new triphosphate CuNa<jats:sub>3</jats:sub>P<jats:sub>3</jats:sub>O<jats:sub>10</jats:sub> and two cyclotriphosphates SrRbP<jats:sub>3</jats:sub>O<jats:sub>9</jats:sub>·3H<jats:sub>2</jats:sub>O and SrRbP<jats:sub>3</jats:sub>O<jats:sub>9</jats:sub>. SrRbP<jats:sub>3</jats:sub>O<jats:sub>9</jats:sub>·3H<jats:sub>2</jats:sub>O was prepared by the method of ion-exchange resin, while CuNa<jats:sub>3</jats:sub>P<jats:sub>3</jats:sub>O<jats:sub>10</jats:sub> and SrRbP<jats:sub>3</jats:sub>O<jats:sub>9</jats:sub> were obtained by total dehydration of CuNa<jats:sub>3</jats:sub>P<jats:sub>3</jats:sub>O<jats:sub>10</jats:sub>·12H<jats:sub>2</jats:sub>O and SrRbP<jats:sub>3</jats:sub>O<jats:sub>9</jats:sub>·3H<jats:sub>2</jats:sub>O, respectively. CuNa<jats:sub>3</jats:sub>P<jats:sub>3</jats:sub>O<jats:sub>10</jats:sub> crystallizes in the hexagonal system, with space group <jats:italic>P</jats:italic>-3<jats:sub>1</jats:sub><jats:italic>c</jats:italic>, <jats:italic>Z</jats:italic>=2, and the following unit-cell dimensions: <jats:italic>a</jats:italic>=<jats:italic>b</jats:italic>=7.022(1) Å, <jats:italic>c</jats:italic>=9.217(1) Å, <jats:italic>M</jats:italic>(20)=81, <jats:italic>F</jats:italic>(20)=117(0.003 419, 50), and <jats:italic>V</jats:italic>=393.24(2) Å<jats:sup>3</jats:sup>. SrRbP<jats:sub>3</jats:sub>O<jats:sub>9</jats:sub>·3H<jats:sub>2</jats:sub>O is orthorhombic, with <jats:italic>Z</jats:italic>=4, space group <jats:italic>P</jats:italic><jats:italic>n</jats:italic><jats:italic>m</jats:italic><jats:italic>a</jats:italic>, and the following unit-cell dimensions: <jats:italic>a</jats:italic>=9.120(1) Å, <jats:italic>b</jats:italic>=8.141(1) Å, <jats:italic>c</jats:italic>=15.234(1) Å, <jats:italic>M</jats:italic>(20)=5.1, <jats:italic>F</jats:italic>(20)=5.8(0.0173,199), and <jats:italic>V</jats:italic>=1131.1(3) Å<jats:sup>3</jats:sup>. SrRbP<jats:sub>3</jats:sub>O<jats:sub>9</jats:sub> is monoclinic, with space group <jats:italic>P</jats:italic>2<jats:sub>1</jats:sub>/<jats:italic>m</jats:italic> or <jats:italic>P</jats:italic>2<jats:sub>1</jats:sub>, <jats:italic>Z</jats:italic>=4, and the following unit-cell dimensions: <jats:italic>a</jats:italic>=14.958(3) Å, <jats:italic>b</jats:italic>=8.503(2) Å, <jats:italic>c</jats:italic>=7.898(2) Å, <jats:italic>β</jats:italic>=122.19(2)°, <jats:italic>M</jats:italic>(20)=9.9, <jats:italic>F</jats:italic>(20)=16.5(0.0189, 64), and <jats:italic>V</jats:italic>=850.2(8) Å<jats:sup>3</jats:sup>.</jats:p>
