ZnH10(CN)6 crystallizes in the cubic I23 space group. Zn(1) is bonded in a tetrahedral geometry to two equivalent N(1) and two equivalent N(3) atoms. Both Zn(1)-N(1) bond lengths are 1.99 Å. Both Zn(1)-N(3) bond lengths are 1.99 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one H(1) atom. The C(1)-N(1) bond length is 1.35 Å. The C(1)-N(2) bond length is 1.33 Å. The C(1)-H(1) bond length is 0.95 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one C(3), one N(1), and one N(3) atom. The C(2)-C(3) bond length is 1.49 Å. The C(2)-N(1) bond length is 1.33 Å. The C(2)-N(3) bond length is 1.33 Å. In the third C site, C(3) is bonded in a trigonal non-coplanar geometry to one C(2); one H(5); and two equivalent H(2,4) atoms. The C(3)-H(5) bond length is 0.98 Å. Both C(3)-H(2,4) bond lengths are 0.98 Å. There are three inequivalent N sites. In the first N site, N(3) is bonded in a 3-coordinate geometry to one Zn(1), one C(2), and one N(2) atom. The N(3)-N(2) bond length is 1.35 Å. In the second N site, N(1) is bonded in a trigonal planar geometry to one Zn(1), one C(1), and one C(2) atom. In the third N site, N(2) is bonded in a 3-coordinate geometry to one C(1), one N(3), and one H(3) atom. The N(2)-H(3) bond length is 0.95 Å. There are four inequivalent H sites. In the first H site, H(3) is bonded in a single-bond geometry to one N(2) atom. In the second H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the third H site, H(2,4) is bonded in a single-bond geometry to one C(3) atom. In the fourth H site, H(5) is bonded in a single-bond geometry to one C(3) atom.
