摘要：

The isotypic compounds K8In11, Rb8In11, K8Tl11, and Rb8Tl11 were prepared from the elements. The crystal structures were determined by single crystal X-ray diffraction methods. (K8In11: a = 1002.1(3), c = 5089.1(8) pm; Rb8In11: a = 1030.1(3), c = 5236.7(7) pm; K8Tl11: a = 999.1(3), c = 5084.8(7) pm; Rb8Tl11: a = 1028.0(3), c = 5230.5(7) pm, R3cBAR, Z = 6). The crystal structures contain In11- and Tl11-clusters, respectively, of pentacapped trigonal prisms. Band structure calculations on K8In11 confirm an [In11]7--''anion'', with one excess electron per In11-cluster involved in alkalimetal-earthmetal bonding.
