Materials Data on Y6CoBr10 by Materials Project

Y6CoBr10 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Y sites. In the first Y site, Y is bonded to one Co and five Br atoms to form a mixture of edge and corner-sharing YCoBr5 octahedra. The corner-sharing octahedra tilt angles range from 0–6°. The Y–Co bond length is 2.56 Å. There are a spread of Y–Br bond distances ranging from 2.85–3.10 Å. In the second Y site, Y is bonded to one Co and five Br atoms to form a mixture of edge and corner-sharing YCoBr5 octahedra. The corner-sharing octahedra tilt angles range from 0–6°. The Y–Co bond length is 2.65 Å. There are a spread of Y–Br bond distances ranging from 2.91–3.09 Å. In the third Y site, Y is bonded to one Co and five Br atoms to form a mixture of edge and corner-sharing YCoBr5 octahedra. The corner-sharing octahedra tilt angles range from 0–4°. The Y–Co bond length is 2.68 Å. There are a spread of Y–Br bond distances ranging from 2.80–3.08 Å. Co is bonded in an octahedral geometry to six Y atoms. There are five inequivalent Br sites. In the first Br site, Br is bonded in a T-shaped geometry to three Y atoms. In the second Br site, Br is bonded in a see-saw-like geometry to four Y atoms. In the third Br site, Br is bonded in a 3-coordinate geometry to three Y atoms. In the fourth Br site, Br is bonded in a T-shaped geometry to three Y atoms. In the fifth Br site, Br is bonded in an L-shaped geometry to two Y atoms.
