Materials Data on CoMoP by Materials Project

Abstract

CoMoP is Matlockite-like structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mo2+ is bonded to five equivalent P3- atoms to form distorted MoP5 trigonal bipyramids that share corners with eight equivalent CoP4 tetrahedra, corners with eight equivalent MoP5 trigonal bipyramids, edges with six equivalent CoP4 tetrahedra, and edges with six equivalent MoP5 trigonal bipyramids. There are a spread of Mo–P bond distances ranging from 2.38–2.63 Å. Co1+ is bonded to four equivalent P3- atoms to form CoP4 tetrahedra that share corners with eight equivalent CoP4 tetrahedra, corners with eight equivalent MoP5 trigonal bipyramids, edges with two equivalent CoP4 tetrahedra, and edges with six equivalent MoP5 trigonal bipyramids. There are a spread of Co–P bond distances ranging from 2.20–2.32 Å. P3- is bonded in a 9-coordinate geometry to five equivalent Mo2+ and four equivalent Co1+ atoms.
