Cs2Sn(NH2)6 crystallizes in the trigonal P-3 space group. Cs(1) is bonded to three equivalent N(1), three equivalent H(2), and six equivalent H(1) atoms to form distorted CsH9N3 cuboctahedra that share corners with three equivalent Sn(1)N6 octahedra and edges with three equivalent Cs(1)H9N3 cuboctahedra. The corner-sharing octahedral tilt angles are 74°. Sn(1) is bonded to six equivalent N(1) atoms to form SnN6 octahedra that share corners with six equivalent Cs(1)H9N3 cuboctahedra. N(1) is bonded in a distorted water-like geometry to one Cs(1), one Sn(1), one H(1), and one H(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to two equivalent Cs(1) and one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one Cs(1) and one N(1) atom.
