ZnC3N8H3CH crystallizes in the monoclinic C2/m space group. The structure consists of four 02329_fluka molecules inside a ZnC3N8H3 framework. In the ZnC3N8H3 framework, Zn(1) is bonded in an octahedral geometry to two equivalent N(1), two equivalent N(2), and two equivalent N(4) atoms. Both Zn(1)-N(1) bond lengths are 2.20 Å. Both Zn(1)-N(2) bond lengths are 2.16 Å. Both Zn(1)-N(4) bond lengths are 2.15 Å. There are two inequivalent C sites. In the first C site, C(1) is bonded in a distorted trigonal planar geometry to one N(1) and one H(1) atom. The C(1)-N(1) bond length is 1.35 Å. The C(1)-H(1) bond length is 1.09 Å. In the second C site, C(3) is bonded in a trigonal planar geometry to two equivalent N(1) and one H(3) atom. Both C(3)-N(1) bond lengths are 1.34 Å. The C(3)-H(3) bond length is 1.09 Å. There are five inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Zn(1), one C(1), and one C(3) atom. In the second N site, N(2) is bonded in a bent 120 degrees geometry to one Zn(1) and one N(3) atom. The N(2)-N(3) bond length is 1.18 Å. In the third N site, N(3) is bonded in a linear geometry to two equivalent N(2) atoms. In the fourth N site, N(4) is bonded in a bent 120 degrees geometry to one Zn(1) and one N(5) atom. The N(4)-N(5) bond length is 1.18 Å. In the fifth N site, N(5) is bonded in a linear geometry to two equivalent N(4) atoms. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(3) is bonded in a single-bond geometry to one C(3) atom. Linkers: 2 c1cncnc1.
