Materials Data on Ba(Cu5P2)2 by Materials Project
Ba(Cu5P2)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ba2+ is bonded in a 7-coordinate geometry to seven P3- atoms. There are a spread of Ba–P bond distances ranging from 3.18–3.33 Å. There are ten inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded in a 3-coordinate geometry to three P3- atoms. There are one shorter (2.26 Å) and two longer (2.41 Å) Cu–P bond lengths. In the second Cu1+ site, Cu1+ is bonded in a distorted trigonal non-coplanar geometry to three P3- atoms. There are one shorter (2.32 Å) and two longer (2.41 Å) Cu–P bond lengths. In the third Cu1+ site, Cu1+ is bonded in a bent 120 degrees geometry to two P3- atoms. There are one shorter (2.38 Å) and one longer (2.42 Å) Cu–P bond lengths. In the fourth Cu1+ site, Cu1+ is bonded in a distorted water-like geometry to three P3- atoms. There are two shorter (2.37 Å) and one longer (2.91 Å) Cu–P bond lengths. In the fifth Cu1+ site, Cu1+ is bonded in a bent 120 degrees geometry to two equivalent P3- atoms. Both Cu–P bond lengths are 2.33 Å. In the sixth Cu1+ site, Cu1+ is bonded in a distorted bent 150 degrees geometry to two P3- atoms. There are one shorter (2.31 Å) and one longer (2.33 Å) Cu–P bond lengths. In the seventh Cu1+ site, Cu1+ is bonded in a distorted trigonal non-coplanar geometry to three P3- atoms. There are one shorter (2.36 Å) and two longer (2.43 Å) Cu–P bond lengths. In the eighth Cu1+ site, Cu1+ is bonded in a 3-coordinate geometry to three P3- atoms. There are one shorter (2.28 Å) and two longer (2.50 Å) Cu–P bond lengths. In the ninth Cu1+ site, Cu1+ is bonded to four P3- atoms to form a mixture of distorted corner and edge-sharing CuP4 tetrahedra. There are a spread of Cu–P bond distances ranging from 2.38–2.54 Å. In the tenth Cu1+ site, Cu1+ is bonded in a distorted trigonal planar geometry to three P3- atoms. There are two shorter (2.33 Å) and one longer (2.40 Å) Cu–P bond lengths. There are four inequivalent P3- sites. In the first P3- site, P3- is bonded in a 9-coordinate geometry to two equivalent Ba2+ and seven Cu1+ atoms. In the second P3- site, P3- is bonded in a 7-coordinate geometry to two equivalent Ba2+ and eight Cu1+ atoms. In the third P3- site, P3- is bonded in a 9-coordinate geometry to two equivalent Ba2+ and seven Cu1+ atoms. In the fourth P3- site, P3- is bonded in a 7-coordinate geometry to one Ba2+ and six Cu1+ atoms.
