Caesium neodymium sulfate, CsNd(SO4)2

The crystal structure of caesium neodymium(III) sulfate, CsNd(SO4)2, was determined from intensity data collected on a Rigaku tabletop XtaLAB mini II diffractometer at the Inter­national Union of Crystallography Congress 2017, in Hyderabad, India. CsNd(SO4)2 is the fourth crystal structure to be reported in the CsPr(SO4)2 family: the Cs and Nd atoms have site symmetries of 2.. and ..2, respectively. In the extended structure, NdO8 square anti­prisms and SO4 tetra­hedra are connected into layers, which propagate in the (101) plane and CsO14 polyhedra connect the layers into a three-dimensional network.
