Materials Data on ZrTi4(PbO3)5 by Materials Project
ZrTi4(PbO3)5 crystallizes in the orthorhombic Cmm2 space group. The structure is three-dimensional. Zr4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are one shorter (1.95 Å) and four longer (2.11 Å) Zr–O bond lengths. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to five O2- atoms to form distorted corner-sharing TiO5 trigonal bipyramids. There are a spread of Ti–O bond distances ranging from 1.74–2.00 Å. In the second Ti4+ site, Ti4+ is bonded to five O2- atoms to form distorted corner-sharing TiO5 trigonal bipyramids. There is one shorter (1.74 Å) and four longer (2.00 Å) Ti–O bond length. There are three inequivalent Pb2+ sites. In the first Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.49–2.91 Å. In the second Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.51–2.95 Å. In the third Pb2+ site, Pb2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Pb–O bond distances ranging from 2.49–2.91 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Zr4+ and four Pb2+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Ti4+ and two Pb2+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Ti4+ and two equivalent Pb2+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Zr4+, one Ti4+, and two Pb2+ atoms. In the fifth O2- site, O2- is bonded in a single-bond geometry to one Ti4+ and four Pb2+ atoms. In the sixth O2- site, O2- is bonded in a single-bond geometry to one Ti4+ and four Pb2+ atoms.
