Materials Data on YbBr2 by Materials Project

YbBr2 is Hydrophilite structured and crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Yb2+ is bonded to six equivalent Br1- atoms to form a mixture of edge and corner-sharing YbBr6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are four shorter (2.90 Å) and two longer (2.92 Å) Yb–Br bond lengths. Br1- is bonded in a distorted trigonal planar geometry to three equivalent Yb2+ atoms.

Materials Data on YbBr3 by Materials Project

YbBr3 is Aluminum trichloride-like structured and crystallizes in the trigonal R-3 space group. The structure is two-dimensional and consists of three YbBr3 sheets oriented in the (0, 0, 1) direction. Yb3+ is bonded to six equivalent Br1- atoms to form edge-sharing YbBr6 octahedra. There are three shorter (2.88 Å) and three longer (2.89 Å) Yb–Br bond lengths. Br1- is bonded in a water-like geometry to two equivalent Yb3+ atoms.

Materials Data on YbBr2 by Materials Project

YbBr2 is Baddeleyite-like structured and crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Yb2+ is bonded to seven Br1- atoms to form a mixture of distorted edge and corner-sharing YbBr7 pentagonal bipyramids. There are a spread of Yb–Br bond distances ranging from 2.91–3.06 Å. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a distorted trigonal planar geometry to three equivalent Yb2+ atoms. In the second Br1- site, Br1- is bonded to four equivalent Yb2+ atoms to form a mixture of distorted edge and corner-sharing BrYb4 tetrahedra.
