Materials Data on Ca4Rh6Pb19 by Materials Project
Ca4Rh6Pb19 crystallizes in the cubic I23 space group. The structure is three-dimensional. Ca is bonded in a distorted q6 geometry to ten Pb atoms. There are a spread of Ca–Pb bond distances ranging from 3.34–3.58 Å. Rh is bonded in a 7-coordinate geometry to one Rh and six Pb atoms. The Rh–Rh bond length is 2.81 Å. There are a spread of Rh–Pb bond distances ranging from 2.71–2.87 Å. There are three inequivalent Pb sites. In the first Pb site, Pb is bonded in a 4-coordinate geometry to two equivalent Ca and two equivalent Rh atoms. In the second Pb site, Pb is bonded in a tetrahedral geometry to four equivalent Ca atoms. In the third Pb site, Pb is bonded in a 4-coordinate geometry to two equivalent Ca and two equivalent Rh atoms.
