Materials Data on Er2Mn12P7 by Materials Project

Abstract

Er2Mn12P7 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 6-coordinate geometry to six equivalent P atoms. All Er–P bond lengths are 2.83 Å. In the second Er site, Er is bonded in a 6-coordinate geometry to six equivalent P atoms. All Er–P bond lengths are 2.83 Å. There are four inequivalent Mn sites. In the first Mn site, Mn is bonded to four P atoms to form a mixture of corner and edge-sharing MnP4 tetrahedra. There are a spread of Mn–P bond distances ranging from 2.31–2.36 Å. In the second Mn site, Mn is bonded to four P atoms to form a mixture of distorted corner and edge-sharing MnP4 tetrahedra. There are a spread of Mn–P bond distances ranging from 2.23–2.30 Å. In the third Mn site, Mn is bonded to four P atoms to form a mixture of corner and edge-sharing MnP4 tetrahedra. There are a spread of Mn–P bond distances ranging from 2.31–2.34 Å. In the fourth Mn site, Mn is bonded in a 5-coordinate geometry to five P atoms. There are a spread of Mn–P bond distances ranging from 2.43–2.57 Å. There are three inequivalent P sites. In the first P site, P is bonded in a 9-coordinate geometry to two equivalent Er and seven Mn atoms. In the second P site, P is bonded in a 9-coordinate geometry to two equivalent Er and seven Mn atoms. In the third P site, P is bonded in a 3-coordinate geometry to nine Mn atoms.
