Materials Data on Pb2CO4 by Materials Project
Pb2O(CO3) crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 1-coordinate geometry to seven O2- atoms. There are a spread of Pb–O bond distances ranging from 2.21–2.91 Å. In the second Pb2+ site, Pb2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Pb–O bond distances ranging from 2.26–2.69 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.29–1.31 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to two equivalent Pb2+ and one C4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one C4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three Pb2+ and one C4+ atom. In the fourth O2- site, O2- is bonded in a trigonal non-coplanar geometry to three Pb2+ atoms.
