Materials Data on CrPb2 by Materials Project

CrPb2 crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of two CrPb2 sheets oriented in the (1, 0, 0) direction. Cr is bonded in a 7-coordinate geometry to seven Pb atoms. There are a spread of Cr–Pb bond distances ranging from 3.08–3.23 Å. There are two inequivalent Pb sites. In the first Pb site, Pb is bonded to four equivalent Cr atoms to form a mixture of distorted corner and edge-sharing PbCr4 tetrahedra. In the second Pb site, Pb is bonded in a 3-coordinate geometry to three equivalent Cr atoms.
