Materials Data on VRe11B4 by Materials Project
VRe11B4 crystallizes in the orthorhombic Amm2 space group. The structure is two-dimensional and consists of two VRe11B4 sheets oriented in the (0, 1, 0) direction. V is bonded in a 2-coordinate geometry to four equivalent Re and two equivalent B atoms. All V–Re bond lengths are 2.73 Å. Both V–B bond lengths are 2.22 Å. There are six inequivalent Re sites. In the first Re site, Re is bonded in a 2-coordinate geometry to three B atoms. There are two shorter (2.26 Å) and one longer (2.56 Å) Re–B bond lengths. In the second Re site, Re is bonded in a 2-coordinate geometry to three B atoms. There are two shorter (2.26 Å) and one longer (2.58 Å) Re–B bond lengths. In the third Re site, Re is bonded in a 2-coordinate geometry to two equivalent V and three B atoms. There are two shorter (2.28 Å) and one longer (2.46 Å) Re–B bond lengths. In the fourth Re site, Re is bonded in a 2-coordinate geometry to three B atoms. There are two shorter (2.24 Å) and one longer (2.58 Å) Re–B bond lengths. In the fifth Re site, Re is bonded in a distorted L-shaped geometry to two equivalent B atoms. Both Re–B bond lengths are 2.22 Å. In the sixth Re site, Re is bonded in a distorted L-shaped geometry to two equivalent B atoms. Both Re–B bond lengths are 2.24 Å. There are three inequivalent B sites. In the first B site, B is bonded in a 2-coordinate geometry to two equivalent V and six Re atoms. In the second B site, B is bonded in a 6-coordinate geometry to eight Re atoms. In the third B site, B is bonded in a 6-coordinate geometry to eight Re atoms.
