Figure 4
(a) Perspective view of the Rb–Cl and Rb–Na–Cl salt-like structural units in a view along [001] (color codes: Rb1 pink, Rb2 dark green, Rb3 orange, Na1 gold, and Cl light green). (b) Ball-and-stick drawing of the extended salt structure occupying the larger channel. One Na–Cl unit (see the one in yellow) is highlighted as a polyhedral unit. (c) Extended Rb2–Cl salt structural unit forming NaCl-type fragments (top); `cubane'-like fragments formed together with Rb3 (bottom), whereby Rb2 occupies all the corners, Rb3 occupies four of the six faces, while Cl3D occupies the other two faces, and Cl4 occupies eight of the twelve edges. (d) Salt stucture extending along [001], showing the corner-sharing {Na4Cl8} units (Rb2 excluded for clarity). (e) Alternating Rb1 and Cl1 sites in the smaller channel. |
