Abstract
Na2Rb2SiO4 crystallizes in a hitherto unknown A2B2CX4 type of structure. The ortho-silicate anions and sodium cations form a three-dimensional structure of connected tetrahedral and trigonalbipyramidal units. The larger rubidium cations complement the cationic part of the structure and display the motif of corrugated hexagonal layers with Rb-Rb distances of less than 400 pm. Single crystal structure data (space group Pbca, Z = 8, a = 983.20(7), b = 1092.26(6), c = 1113.04(8) pm) are given and a comparison to other A2B2CX4-type of structures is presented.
