Ba₂ErCl₇

S. Tsuchiya, Y. Hanaue, E. Kimura and N. Ishizawa

Dibarium erbium heptachloride has a network structure composed of ErCl₇ and BaCl₉ polyhedra. Since the array of Ba and Er atoms is isostructural with the alloy Co₂Si , the structure can be considered as a stuffed Co₂Si-type structure. The mean bond distances are 2.704 Å for ErCl₇, 3.221 Å for Ba1Cl₉, and 3.212 Å for Ba2Cl₉. Some of the Cl atoms form tunnels running parallel to the c axis.
