Y6CoBr10 crystallizes in the triclinic P-1 space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded to one Co(1), one Br(2), one Br(3), one Br(5), and two equivalent Br(1) atoms to form a mixture of corner and edge-sharing YCoBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-7°. In the second Y site, Y(2) is bonded to one Co(1), one Br(1), one Br(2), one Br(3), and two equivalent Br(4) atoms to form a mixture of corner and edge-sharing YCoBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-7°. In the third Y site, Y(3) is bonded to one Co(1), one Br(3), one Br(4), one Br(5), and two equivalent Br(2) atoms to form a mixture of corner and edge-sharing YCoBr5 octahedra. The corner-sharing octahedral tilt angles range from 0-4°. Co(1) is bonded in an octahedral geometry to two equivalent Y(1), two equivalent Y(2), and two equivalent Y(3) atoms. There are five inequivalent Br sites. In the first Br site, Br(1) is bonded in a T-shaped geometry to one Y(2) and two equivalent Y(1) atoms. In the second Br site, Br(2) is bonded in a see-saw-like geometry to one Y(1), one Y(2), and two equivalent Y(3) atoms. In the third Br site, Br(3) is bonded in a 3-coordinate geometry to one Y(1), one Y(2), and one Y(3) atom. In the fourth Br site, Br(4) is bonded in a T-shaped geometry to one Y(3) and two equivalent Y(2) atoms. In the fifth Br site, Br(5) is bonded in an L-shaped geometry to one Y(1) and one Y(3) atom.
