Zn(CO2)4(N(CH3)2)2 is Indium-derived structured and crystallizes in the orthorhombic C222 space group. The structure is zero-dimensional and consists of eight dimethylazanium molecules and four Zn(CO2)4 clusters. In each Zn(CO2)4 cluster, Zn(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(3) atoms. Both Zn(1)-O(1) bond lengths are 2.02 Å. Both Zn(1)-O(3) bond lengths are 1.95 Å. There are two inequivalent C sites. In the first C site, C(4) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. The C(4)-O(3) bond length is 1.29 Å. The C(4)-O(4) bond length is 1.25 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one O(1) and one O(2) atom. The C(2)-O(1) bond length is 1.29 Å. The C(2)-O(2) 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(2) atom. In the second O site, O(3) is bonded in a bent 120 degrees geometry to one Zn(1) and one C(4) atom. In the third O site, O(4) is bonded in a single-bond geometry to one C(4) atom. In the fourth O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one C(2) atom. Linkers: 4 [O]C(=O)C[NH2]CC(=O)[O]. Metal clusters: 2 O=[C]O[Zn](O[C]=O)(O[C]=O)O[C]=O.
