ZnH8(C2N)4(CH3)2 crystallizes in the trigonal P3_221 space group. The structure consists of six 02329_fluka molecules inside a ZnH8(C2N)4 framework. In the ZnH8(C2N)4 framework, Zn(1) is bonded in a tetrahedral geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Zn(1)-N(1) bond lengths are 2.01 Å. Both Zn(1)-N(2) bond lengths are 2.01 Å. There are four inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one N(1), and one H(1) atom. The C(1)-C(2) bond length is 1.37 Å. The C(1)-N(1) bond length is 1.38 Å. The C(1)-H(1) bond length is 1.08 Å. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one C(1), one N(2), and one H(2) atom. The C(2)-N(2) bond length is 1.38 Å. The C(2)-H(2) bond length is 1.08 Å. In the third C site, C(3) is bonded in a distorted trigonal planar geometry to one C(4), one N(1), and one N(2) atom. The C(3)-C(4) bond length is 1.49 Å. The C(3)-N(1) bond length is 1.35 Å. The C(3)-N(2) bond length is 1.36 Å. In the fourth C site, C(4) is bonded in a distorted water-like geometry to one C(3), one H(3), and one H(4) atom. The C(4)-H(3) bond length is 1.10 Å.
