Materials Data on BaCaPb by Materials Project
BaCaPb crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ba is bonded in a 5-coordinate geometry to five equivalent Pb atoms. There are a spread of Ba–Pb bond distances ranging from 3.65–3.86 Å. Ca is bonded to four equivalent Pb atoms to form a mixture of distorted edge and corner-sharing CaPb4 tetrahedra. There are a spread of Ca–Pb bond distances ranging from 3.30–3.37 Å. Pb is bonded in a 9-coordinate geometry to five equivalent Ba and four equivalent Ca atoms.
