title: Twinned alpha-LiRb2(CF3SO3)3.
abstract: The investigated crystal of alpha-LiRb(2)(CF(3)SO(3))(3) [lithium dirubidium tris(trifluoromethanesulfonate)] was a twin, with the twin matrix given by (-100/010/001). The structure consists of channel-like patterns built up of lipophilic CF(3) groups pointing towards each other. The polar interstices are occupied by cations. One Rb atom is coordinated by O atoms in the form of a distorted square antiprism, while the coordination around the second Rb atom is best described as a distorted pentagonal plane, with one O atom and one F atom situated above and an additional F atom below this plane. The O atoms around the Li atom form a strongly distorted tetrahedron.
