ZnC16NH12O4 is alpha Po structured and crystallizes in the tetragonal I4/mcm space group. The structure is zero-dimensional and consists of four ZnC16NH12O4 clusters. Zn(1) is bonded in a distorted square pyramidal geometry to one N(1) and four equivalent O(1) atoms. The Zn(1)-N(1) bond length is 2.05 Å. All Zn(1)-O(1) bond lengths are 2.04 Å. There are five inequivalent C sites. In the first C site, C(1) is bonded in a distorted single-bond geometry to one C(5) and one H(1) atom. The C(1)-C(5) bond length is 1.38 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(3) is bonded in a distorted single-bond geometry to one N(1), one H(2), and one H(3) atom. The C(3)-N(1) bond length is 1.42 Å. The C(3)-H(2) bond length is 1.16 Å. The C(3)-H(3) bond length is 0.80 Å. In the third C site, C(2) is bonded in a 2-coordinate geometry to one N(1), one H(2), and one H(3) atom. The C(2)-N(1) bond length is 1.45 Å. The C(2)-H(2) bond length is 0.97 Å. The C(2)-H(3) bond length is 0.97 Å. In the fourth C site, C(4) is bonded in a bent 120 degrees geometry to one C(5) and two equivalent O(1) atoms. The C(4)-C(5) bond length is 1.50 Å. Both C(4)-O(1) bond lengths are 1.25 Å. In the fifth C site, C(5) is bonded in a trigonal planar geometry to one C(4) and two equivalent C(1) atoms. N(1) is bonded in a 9-coordinate geometry to one Zn(1), four equivalent C(2), and four equivalent C(3) atoms. There are three inequivalent H sites. In the first H site, H(2) is bonded in a 2-coordinate geometry to one C(2) and one C(3) atom. In the second H site, H(3) is bonded in a 2-coordinate geometry to one C(2) and one C(3) atom. In the third H site, H(1) is bonded in a single-bond geometry to one C(1) atom. O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one C(4) atom.
