The structure described by CsY2Cl7 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 10-coordinate geometry to two equivalent Cl(1), two equivalent Cl(2), two equivalent Cl(4), and four equivalent Cl(3) atoms. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to one Cl(4), two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms to form a mixture of distorted edge and face-sharing YCl7 pentagonal bipyramids. In the second Y site, Y(2) is bonded to one Cl(4), two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(3) atoms to form a mixture of distorted edge and face-sharing YCl7 pentagonal bipyramids. There are four inequivalent Cl sites. In the first Cl site, Cl(4) is bonded to two equivalent Cs(1), one Y(1), and one Y(2) atom to form a mixture of distorted edge and corner-sharing ClCs2Y2 trigonal pyramids. In the second Cl site, Cl(1) is bonded in a distorted L-shaped geometry to one Cs(1), one Y(1), and one Y(2) atom. In the third Cl site, Cl(2) is bonded in a distorted trigonal non-coplanar geometry to one Cs(1), one Y(1), and one Y(2) atom. In the fourth Cl site, Cl(3) is bonded to two equivalent Cs(1), one Y(1), and one Y(2) atom to form a mixture of distorted edge and corner-sharing ClCs2Y2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
