摘要：

Pr-3(SiO4)(2)Cl is isostructural with La-3(SiO4)(2)Cl. The Pr(1)O7Cl polyhedron is irregular. The Pr(2)O8Cl2 polyhedron is a distorted square antiprism with the Cl atom capping distorted square faces. The site of Pr(2) can also be described as at the centre of a Pr(2)(SiO4)(4)Cl-2 octahedron. The structure comprises layers of Pr(2)(SiO4)(4)Cl-2 octahedra separated in the a direction by Pr(1) cations occupying the Pr(1)O7Cl polyhedral sites. The Cl atom is four-coordinate forming a distorted square.
