Materials Data on K2Pb(SO4)2 by Materials Project
K2Pb(SO4)2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. K1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.71–2.99 Å. Pb2+ is bonded in a 12-coordinate geometry to six equivalent O2- atoms. All Pb–O bond lengths are 2.67 Å. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.48 Å) and three longer (1.50 Å) S–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent K1+, one Pb2+, and one S6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one S6+ atom.
