(C4NH8)2ZnC2(O2Cl)2 is Indium-derived structured and crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of eight tetramethylammonium molecules and four ZnC2(O2Cl)2 clusters. In each ZnC2(O2Cl)2 cluster, Zn(1) is bonded in a tetrahedral geometry to one O(1), one O(3), one Cl(1), and one Cl(2) atom. The Zn(1)-O(1) bond length is 1.98 Å. The Zn(1)-O(3) bond length is 2.01 Å. The Zn(1)-Cl(1) bond length is 2.29 Å. The Zn(1)-Cl(2) bond length is 2.22 Å. There are two inequivalent C sites. In the first C site, C(8) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(8)-O(1) bond length is 1.29 Å. The C(8)-O(2) bond length is 1.24 Å. In the second C site, C(9) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. The C(9)-O(3) bond length is 1.29 Å. The C(9)-O(4) bond length is 1.25 Å. There are four inequivalent O sites. In the first O site, O(2) is bonded in a single-bond geometry to one C(8) atom. In the second O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Zn(1) and one C(9) atom. In the third O site, O(4) is bonded in a single-bond geometry to one C(9) atom. In the fourth O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one C(8) atom. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Zn(1) atom. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Zn(1) atom.
