The crystal structure described by K2YCl5 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Cl(1), two equivalent Cl(2), two equivalent Cl(3), and two equivalent Cl(4) atoms. Y(1) is bonded to one Cl(1), one Cl(2), one Cl(3), and four equivalent Cl(4) atoms to form distorted edge-sharing YCl7 pentagonal bipyramids. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to four equivalent K(1) and one Y(1) atom to form a mixture of distorted edge, corner, and face-sharing ClK4Y trigonal bipyramids. In the second Cl site, Cl(2) is bonded to four equivalent K(1) and one Y(1) atom to form a mixture of distorted edge and corner-sharing ClK4Y trigonal bipyramids. In the third Cl site, Cl(3) is bonded to four equivalent K(1) and one Y(1) atom to form a mixture of distorted edge, corner, and face-sharing ClK4Y trigonal bipyramids. In the fourth Cl site, Cl(4) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Y(1) atoms. is represented by the CIF file [CIF]
