Materials Data on CoMoP by Materials Project

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.

Materials Data on CoMoP2 by Materials Project

MoCoP2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Mo4+ is bonded to six equivalent P3- atoms to form distorted MoP6 pentagonal pyramids that share corners with twelve equivalent CoP6 octahedra, edges with six equivalent MoP6 pentagonal pyramids, and faces with two equivalent CoP6 octahedra. The corner-sharing octahedral tilt angles are 48°. All Mo–P bond lengths are 2.48 Å. Co2+ is bonded to six equivalent P3- atoms to form CoP6 octahedra that share corners with twelve equivalent MoP6 pentagonal pyramids, edges with six equivalent CoP6 octahedra, and faces with two equivalent MoP6 pentagonal pyramids. All Co–P bond lengths are 2.26 Å. P3- is bonded in a 6-coordinate geometry to three equivalent Mo4+ and three equivalent Co2+ atoms.
