Rb2BaCl4 crystallizes in the tetragonal I-42d space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent Cl(1) atoms. Ba(1) is bonded to eight equivalent Cl(1) atoms to form distorted edge-sharing BaCl8 hexagonal bipyramids. Cl(1) is bonded to four equivalent Rb(1) and two equivalent Ba(1) atoms to form a mixture of distorted edge, face, and corner-sharing ClRb4Ba2 octahedra. The corner-sharing octahedral tilt angles range from 14-53°.
Rb2BaCl4 crystallizes in the tetragonal I-42d space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent Cl(1) atoms. There are a spread of Rb(1)-Cl(1) bond distances ranging from 3.24-3.53 Å. Ba(1) is bonded to eight equivalent Cl(1) atoms to form distorted edge-sharing BaCl8 hexagonal bipyramids. There are four shorter (3.16 Å) and four longer (3.41 Å) Ba(1)-Cl(1) bond lengths. Cl(1) is bonded to four equivalent Rb(1) and two equivalent Ba(1) atoms to form a mixture of distorted edge, face, and corner-sharing ClRb4Ba2 octahedra. The corner-sharing octahedral tilt angles range from 14-53°.
