ZnC26NO4 is Indium-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one ZnC26NO4 cluster. Zn(1) is bonded in a square pyramidal geometry to one N(1) and four equivalent O(1) atoms. The Zn(1)-N(1) bond length is 2.00 Å. All Zn(1)-O(1) bond lengths are 2.00 Å. There are six inequivalent C sites. In the first C site, C(1) is bonded in a 3-coordinate geometry to one C(1), one C(2), and one C(3) atom. The C(1)-C(1) bond length is 1.50 Å. The C(1)-C(2) bond length is 1.34 Å. The C(1)-C(3) bond length is 1.25 Å. In the second C site, C(4) is bonded in a 5-coordinate geometry to one C(5) and four equivalent C(2) atoms. The C(4)-C(5) bond length is 1.37 Å. All C(4)-C(2) bond lengths are 1.58 Å. In the third C site, C(2) is bonded in a 3-coordinate geometry to one C(1), one C(2), and one C(4) atom. The C(2)-C(2) bond length is 1.41 Å. In the fourth C site, C(3) is bonded in a 4-coordinate geometry to four equivalent C(1) atoms. In the fifth C site, C(5) is bonded in a distorted bent 120 degrees geometry to one C(4) and two equivalent O(1) atoms. Both C(5)-O(1) bond lengths are 1.26 Å. In the sixth C site, C(6) is bonded in a single-bond geometry to one N(1) atom. The C(6)-N(1) bond length is 1.45 Å. N(1) is bonded in a 5-coordinate geometry to one Zn(1) and four equivalent C(6) atoms. O(1) is bonded in a bent 120 degrees geometry to one Zn(1) and one C(5) atom.
