The crystal structure described by Cu8NO11 crystallizes in the orthorhombic Fmm2 space group. There are five inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Cu site, Cu(2) is bonded in a 6-coordinate geometry to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms. In the third Cu site, Cu(3) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. In the fourth Cu site, Cu(4) is bonded in a distorted square co-planar geometry to one O(4), two equivalent O(1), and two equivalent O(2) atoms. In the fifth Cu site, Cu(5) is bonded in a distorted square co-planar geometry to four equivalent O(2) atoms. N(1) is bonded in a trigonal planar geometry to one O(4) and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Cu(1), one Cu(2), one Cu(3), and one Cu(4) atom to form a mixture of corner and edge-sharing OCu4 trigonal pyramids. In the second O site, O(2) is bonded to one Cu(1), one Cu(2), one Cu(4), and one Cu(5) atom to form a mixture of corner and edge-sharing OCu4 trigonal pyramids. In the third O site, O(3) is bonded in a 1-coordinate geometry to one Cu(2) and one N(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Cu(2), two equivalent Cu(4), and one N(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
