Materials Data on B5Ir3W2 by Materials Project

W2Ir3B5 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. W2+ is bonded in a 7-coordinate geometry to six B3- atoms. There are a spread of W–B bond distances ranging from 2.22–2.31 Å. There are two inequivalent Ir+3.67+ sites. In the first Ir+3.67+ site, Ir+3.67+ is bonded in an L-shaped geometry to two equivalent B3- atoms. Both Ir–B bond lengths are 2.18 Å. In the second Ir+3.67+ site, Ir+3.67+ is bonded in a 4-coordinate geometry to four B3- atoms. There are one shorter (2.20 Å) and three longer (2.21 Å) Ir–B bond lengths. There are three inequivalent B3- sites. In the first B3- site, B3- is bonded in a 7-coordinate geometry to three equivalent W2+, one Ir+3.67+, and three equivalent B3- atoms. There is two shorter (1.77 Å) and one longer (1.89 Å) B–B bond length. In the second B3- site, B3- is bonded in a 7-coordinate geometry to three equivalent W2+, one Ir+3.67+, and three equivalent B3- atoms. In the third B3- site, B3- is bonded in a 6-coordinate geometry to six Ir+3.67+ atoms.
