Materials Data on YCBr by Materials Project

YCBr crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Y3+ is bonded in a 4-coordinate geometry to four equivalent C2- and four equivalent Br1- atoms. There are two shorter (2.47 Å) and two longer (2.54 Å) Y–C bond lengths. There are a spread of Y–Br bond distances ranging from 3.08–3.20 Å. C2- is bonded to four equivalent Y3+ and one Br1- atom to form a mixture of edge and corner-sharing CY4Br trigonal bipyramids. The C–Br bond length is 2.29 Å. Br1- is bonded in a 1-coordinate geometry to four equivalent Y3+ and one C2- atom.

Materials Data on YCBr by Materials Project

YCBr crystallizes in the monoclinic C2/m space group. The structure is two-dimensional and consists of one YCBr sheet oriented in the (0, 0, 1) direction. Y3+ is bonded in a 8-coordinate geometry to five equivalent C2- and three equivalent Br1- atoms. There are a spread of Y–C bond distances ranging from 2.34–2.65 Å. There are two shorter (2.91 Å) and one longer (3.08 Å) Y–Br bond lengths. C2- is bonded in a 6-coordinate geometry to five equivalent Y3+ and one C2- atom. The C–C bond length is 1.34 Å. Br1- is bonded in a 3-coordinate geometry to three equivalent Y3+ atoms.
