Materials Data on B2H5 by Materials Project
B2H5 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four B2H5 clusters. there are four inequivalent B sites. In the first B site, B is bonded in a distorted tetrahedral geometry to four H atoms. There is two shorter (1.20 Å) and two longer (1.41 Å) B–H bond length. In the second B site, B is bonded in a distorted trigonal non-coplanar geometry to three H atoms. There is one shorter (1.19 Å) and two longer (1.27 Å) B–H bond length. In the third B site, B is bonded in a distorted tetrahedral geometry to four H atoms. There is two shorter (1.20 Å) and two longer (1.41 Å) B–H bond length. In the fourth B site, B is bonded in a distorted trigonal non-coplanar geometry to three H atoms. There is one shorter (1.19 Å) and two longer (1.27 Å) B–H bond length. There are ten inequivalent H sites. In the first H site, H is bonded in a single-bond geometry to one B atom. In the second H site, H is bonded in an L-shaped geometry to two B atoms. In the third H site, H is bonded in a single-bond geometry to one B atom. In the fourth H site, H is bonded in a single-bond geometry to one B atom. In the fifth H site, H is bonded in an L-shaped geometry to two B atoms. In the sixth H site, H is bonded in an L-shaped geometry to two B atoms. In the seventh H site, H is bonded in a single-bond geometry to one B atom. In the eighth H site, H is bonded in a single-bond geometry to one B atom. In the ninth H site, H is bonded in a single-bond geometry to one B atom. In the tenth H site, H is bonded in an L-shaped geometry to two B atoms.
