The material described by K2Pb(SO4)2 is Copper structured and crystallizes in the trigonal R-3m space group. The structure is zero-dimensional and consists of three K2Pb(SO4)2 clusters. K(1) is bonded in a single-bond geometry to one O(2) atom. Pb(1) is bonded in a distorted hexagonal planar geometry to six equivalent O(1) atoms. S(1) is bonded in a tetrahedral geometry to one O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Pb(1) and one S(1) atom. In the second O site, O(2) is bonded in a linear geometry to one K(1) and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
