[BMIm]4[Sn9Se20]: ionothermal synthesis of a selenidostannate with a 3D open-framework structure
1Fachbereich Chemie, Philipps-Universität Marburg, Hans-Meerwein Strasse, 35043 Marburg, Germany.
Abstract:
The reaction of [K(4)(H(2)O)(4)][SnSe(4)] with [BMIm][BF(4)] at 130-180 °C afforded [BMIm](4)[Sn(9)Se(20)] (1). The anion of the title compound represents a unique three-dimensional (3D) open framework, based on a variety of interconnectivity modes of Sn/Se units that lead to a system of six intersecting channels. 1 comprises the first example of a binary 3D open-framework selenidostannate anion and the first 3D open-framework chalcogenido metalate to be conveniently obtained by ionothermal synthesis.
