The crystal structure described by KGd2Cl7 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 8-coordinate geometry to one Cl(2), one Cl(3), one Cl(4), one Cl(5), one Cl(6), one Cl(7), and two equivalent Cl(1) atoms. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded to one Cl(1), one Cl(2), one Cl(3), one Cl(4), one Cl(5), one Cl(6), and one Cl(7) atom to form a mixture of distorted edge and face-sharing GdCl7 pentagonal bipyramids. In the second Gd site, Gd(2) is bonded to one Cl(1), one Cl(2), one Cl(3), one Cl(4), one Cl(5), one Cl(6), and one Cl(7) atom to form a mixture of distorted edge and face-sharing GdCl7 pentagonal bipyramids. There are seven inequivalent Cl sites. In the first Cl site, Cl(6) is bonded in a distorted T-shaped geometry to one K(1), one Gd(1), and one Gd(2) atom. In the second Cl site, Cl(7) is bonded in a trigonal non-coplanar geometry to one K(1), one Gd(1), and one Gd(2) atom. In the third Cl site, Cl(1) is bonded in a 3-coordinate geometry to two equivalent K(1), one Gd(1), and one Gd(2) atom. In the fourth Cl site, Cl(2) is bonded in a 3-coordinate geometry to one K(1), one Gd(1), and one Gd(2) atom. In the fifth Cl site, Cl(3) is bonded in a distorted L-shaped geometry to one K(1), one Gd(1), and one Gd(2) atom. In the sixth Cl site, Cl(4) is bonded in a trigonal non-coplanar geometry to one K(1), one Gd(1), and one Gd(2) atom. In the seventh Cl site, Cl(5) is bonded in a trigonal non-coplanar geometry to one K(1), one Gd(1), and one Gd(2) atom. is represented by the CIF file [CIF]
