KSiH3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 9-coordinate geometry to three equivalent H(2) and six equivalent H(1) atoms. Si(1) is bonded in a 3-coordinate geometry to one H(2) and two equivalent H(1) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded to three equivalent K(1) and one Si(1) atom to form a mixture of distorted corner and edge-sharing HK3Si tetrahedra. In the second H site, H(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Si(1) atom.
KSiH3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 9-coordinate geometry to three equivalent H(2) and six equivalent H(1) atoms. There is one shorter (2.89 Å) and two longer (2.91 Å) K(1)-H(2) bond lengths. There are a spread of K(1)-H(1) bond distances ranging from 2.76-2.82 Å. Si(1) is bonded in a 3-coordinate geometry to one H(2) and two equivalent H(1) atoms. The Si(1)-H(2) bond length is 1.53 Å. Both Si(1)-H(1) bond lengths are 1.54 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded to three equivalent K(1) and one Si(1) atom to form a mixture of distorted corner and edge-sharing HK3Si tetrahedra. In the second H site, H(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Si(1) atom.
