K2SrCl4 crystallizes in the trigonal R-3m space group. K(1) is bonded in a 8-coordinate geometry to four equivalent Cl(1) and four equivalent Cl(2) atoms. Sr(1) is bonded in a body-centered cubic geometry to two equivalent Cl(1) and six equivalent Cl(2) atoms. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to four equivalent K(1) and one Sr(1) atom to form a mixture of corner and edge-sharing ClK4Sr trigonal bipyramids. In the second Cl site, Cl(2) is bonded in a 7-coordinate geometry to four equivalent K(1) and three equivalent Sr(1) atoms.
K2SrCl4 crystallizes in the trigonal R-3m space group. K(1) is bonded in a 8-coordinate geometry to four equivalent Cl(1) and four equivalent Cl(2) atoms. There are three shorter (3.08 Å) and one longer (3.24 Å) K(1)-Cl(1) bond length. There is one shorter (3.50 Å) and three longer (3.71 Å) K(1)-Cl(2) bond lengths. Sr(1) is bonded in a body-centered cubic geometry to two equivalent Cl(1) and six equivalent Cl(2) atoms. Both Sr(1)-Cl(1) bond lengths are 2.95 Å. All Sr(1)-Cl(2) bond lengths are 3.16 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to four equivalent K(1) and one Sr(1) atom to form a mixture of corner and edge-sharing ClK4Sr trigonal bipyramids. In the second Cl site, Cl(2) is bonded in a 7-coordinate geometry to four equivalent K(1) and three equivalent Sr(1) atoms.
