KBH4 crystallizes in the orthorhombic Pmmn space group. K(1) is bonded in a 12-coordinate geometry to six equivalent H(1) and six equivalent H(2) atoms. B(1) is bonded in a tetrahedral geometry to two equivalent H(1) and two equivalent H(2) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to three equivalent K(1) and one B(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to three equivalent K(1) and one B(1) atom.
KBH4 crystallizes in the orthorhombic Pmmn space group. K(1) is bonded in a 12-coordinate geometry to six equivalent H(1) and six equivalent H(2) atoms. There are two shorter (2.76 Å) and four longer (2.78 Å) K(1)-H(1) bond lengths. There are two shorter (2.75 Å) and four longer (2.78 Å) K(1)-H(2) bond lengths. B(1) is bonded in a tetrahedral geometry to two equivalent H(1) and two equivalent H(2) atoms. Both B(1)-H(1) bond lengths are 1.23 Å. Both B(1)-H(2) bond lengths are 1.22 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to three equivalent K(1) and one B(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to three equivalent K(1) and one B(1) atom.
