Be(OH)2 crystallizes in the orthorhombic P2_12_12_1 space group. Be(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing BeO4 tetrahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Be(1) and one H(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Be(1) and one H(2) atom.
Be(OH)2 crystallizes in the orthorhombic P2_12_12_1 space group. Be(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing BeO4 tetrahedra. Both Be(1)-O(1) bond lengths are 1.64 Å. There is one shorter (1.62 Å) and one longer (1.65 Å) Be(1)-O(2) bond length. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. The H(1)-O(1) bond length is 0.98 Å. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. The H(2)-O(2) bond length is 0.98 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Be(1) and one H(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Be(1) and one H(2) atom.
