KBeH3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 7-coordinate geometry to two equivalent H(1), two equivalent H(3), and three equivalent H(2) atoms. Be(1) is bonded in a trigonal planar geometry to one H(1), one H(2), and one H(3) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Be(1) atom. In the second H site, H(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Be(1) atom. In the third H site, H(3) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Be(1) atom.
KBeH3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 7-coordinate geometry to two equivalent H(1), two equivalent H(3), and three equivalent H(2) atoms. There is one shorter (2.71 Å) and one longer (2.78 Å) K(1)-H(1) bond length. There is one shorter (2.68 Å) and one longer (2.89 Å) K(1)-H(3) bond length. There are a spread of K(1)-H(2) bond distances ranging from 2.67-2.89 Å. Be(1) is bonded in a trigonal planar geometry to one H(1), one H(2), and one H(3) atom. The Be(1)-H(1) bond length is 1.40 Å.
