Cu9O2(SeO3)4Cl6 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are five inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Cu–O bond distances ranging from 1.94–2.53 Å. In the second Cu2+ site, Cu2+ is bonded in a 4-coordinate geometry to two O2- and two Cl1- atoms. There is one shorter (1.97 Å) and one longer (1.99 Å) Cu–O bond length. There are one shorter (2.21 Å) and one longer (2.25 Å) Cu–Cl bond lengths. In the third Cu2+ site, Cu2+ is bonded in a distorted trigonal bipyramidal geometry to four O2- and one Cl1- atom. There are a spread of Cu–O bond distances ranging from 1.98–2.13 Å. The Cu–Cl bond length is 2.30 Å. In the fourth Cu2+ site, Cu2+ is bonded in a distorted square co-planar geometry to four O2- atoms. There is two shorter (1.94 Å) and two longer (2.01 Å) Cu–O bond length. In the fifth Cu2+ site, Cu2+ is bonded in a square co-planar geometry to two equivalent O2- and two equivalent Cl1- atoms. Both Cu–O bond lengths are 1.91 Å. Both Cu–Cl bond lengths are 2.34 Å. There are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.74 Å) and one longer (1.75 Å) Se–O bond length. In the second Se4+ site, Se4+ is bonded in a distorted T-shaped geometry to three O2- atoms. There are a spread of Se–O bond distances ranging from 1.74–1.79 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two Cu2+ and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cu2+ and one Se4+ atom. In the third O2- site, O2- is bonded to four Cu2+ atoms to form corner-sharing OCu4 tetrahedra. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two Cu2+ and one Se4+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Cu2+ and one Se4+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Cu2+ and one Se4+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cu2+ and one Se4+ atom. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in an L-shaped geometry to two Cu2+ atoms. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Cu2+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one Cu2+ atom.
