Materials Data on Pb(CO3)2 by Materials Project

Abstract

Pb(CO3)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional and consists of four hydrogen peroxide molecules and one PbC2O4 framework. In the PbC2O4 framework, Pb4+ is bonded in a 6-coordinate geometry to six O2- atoms. There are four shorter (2.48 Å) and two longer (2.84 Å) Pb–O bond lengths. C4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.28 Å) C–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Pb4+ and one C4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Pb4+ and one C4+ atom.
