Zn4C12N6H6O7 crystallizes in the cubic F23 space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to three equivalent N(1) and one O(1) atom to form corner-sharing ZnN3O trigonal pyramids. All Zn(1)-N(1) bond lengths are 2.01 Å. The Zn(1)-O(1) bond length is 1.96 Å. In the second Zn site, Zn(2) is bonded to one O(2) and three equivalent O(3) atoms to form corner-sharing ZnO4 tetrahedra. The Zn(2)-O(2) bond length is 1.96 Å. All Zn(2)-O(3) bond lengths are 1.97 Å. There are three inequivalent C sites. In the first C site, C(3) is bonded in a distorted bent 120 degrees geometry to one C(1) and two equivalent O(3) atoms. The C(3)-C(1) bond length is 1.47 Å. Both C(3)-O(3) bond lengths are 1.28 Å. In the second C site, C(1) is bonded in a trigonal planar geometry to one C(3) and two equivalent C(2) atoms. Both C(1)-C(2) bond lengths are 1.40 Å. In the third C site, C(2) is bonded in a distorted bent 120 degrees geometry to one C(1), one N(1), and one H(1) atom. The C(2)-N(1) bond length is 1.34 Å. The C(2)-H(1) bond length is 1.09 Å. N(1) is bonded in a 2-coordinate geometry to one Zn(1) and one C(2) atom. H(1) is bonded in a single-bond geometry to one C(2) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a tetrahedral geometry to four equivalent Zn(1) atoms. In the second O site, O(2) is bonded in a tetrahedral geometry to four equivalent Zn(2) atoms. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Zn(2) and one C(3) atom.
