Materials Data on TbCo3P2 by Materials Project
Abstract
TbCo3P2 crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. there are two inequivalent Tb3+ sites. In the first Tb3+ site, Tb3+ is bonded to six P3- atoms to form distorted TbP6 pentagonal pyramids that share corners with four equivalent TbP6 pentagonal pyramids, corners with twelve CoP4 tetrahedra, edges with two equivalent TbP6 pentagonal pyramids, edges with eight CoP4 tetrahedra, and faces with two equivalent TbP6 pentagonal pyramids. There are two shorter (2.86 Å) and four longer (2.95 Å) Tb–P bond lengths. In the second Tb3+ site, Tb3+ is bonded to six P3- atoms to form distorted TbP6 pentagonal pyramids that share corners with four TbP6 pentagonal pyramids, corners with twelve CoP4 tetrahedra, edges with two TbP6 pentagonal pyramids, edges with seven CoP4 tetrahedra, and faces with two equivalent TbP6 pentagonal pyramids. There are a spread of Tb–P bond distances ranging from 2.81–2.89 Å. There are six inequivalent Co1+ sites. In the first Co1+ site, Co1+ is bonded in a 5-coordinate geometry to five P3- atoms. There are one shorter (2.25 Å) and four longer (2.53 Å) Co–P bond lengths. In the second Co1+ site, Co1+ is bonded in a trigonal planar geometry to three P3- atoms. Theremore »
