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)2is the fourth crystal structure to be reported in the CsPr(SO4)2family: the Cs and Nd atoms have site symmetries of 2.. and ..2, respectively. In the extended structure, NdO8square antiprisms and SO4tetrahedra are connected into layers, which propagate in the (101) plane and CsO14polyhedra connect the layers into a three-dimensional network.
