KMo2O2Cl7 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 10-coordinate geometry to two equivalent O(1), two equivalent Cl(1), two equivalent Cl(2), and four equivalent Cl(4) atoms. Mo(1) is bonded in a 6-coordinate geometry to one O(1), one Cl(2), one Cl(3), one Cl(4), and two equivalent Cl(1) atoms. O(1) is bonded in a distorted linear geometry to one K(1) and one Mo(1) atom. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Mo(1) atoms. In the second Cl site, Cl(2) is bonded in a distorted water-like geometry to one K(1) and one Mo(1) atom. In the third Cl site, Cl(3) is bonded in an L-shaped geometry to two equivalent Mo(1) atoms. In the fourth Cl site, Cl(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent K(1) and one Mo(1) atom.
