Abstract
Structural investigation of cesium zinc monophosphate CsZnPO4 has been carried out at three different temperatures. At room temperature, this salt is monoclinic, P21/a with a = 18.33(8), b = 5.45(4), c = 9.25(6) Å, β. = 90.14(8)° and Z = 8 (form III):at 260°C, it becomes orthorhombic, Pn21a with a = 9.246(9), b = 5.468(6), c = 9.359(7) Å and Z = 4 (form II),at 310°C, it is orthorhombic Pnma with a = 9.191(5), b = 5.493(5), c = 9.406(5) Å = Z = 4 (form I). Crystal structures of these three forms have been solved and refined with final R values: R = .043 (at room temperature) for 2914 independent reflections, R = .041 (at T = 280°C) for 735 independent reflections, R = .042 (at T = 340°C) for 644 independent reflections.Keywords
