Abstract
A new layered borosilicate has been synthesized in the presence of cesium and sodium cations and its structure has been solved by a combination of automated diffraction tomography (ADT) and X-ray powder diffraction (XRPD). MZ-35 has a composition NaCs2[BSi7O16(OH)(2)KOH)(2)]center dot 4H(2)O and features space group P-4m2. The unusually small unit cell (a 7.3081 angstrom, c 10.7520 angstrom) is shared by two random-stacked configurations of the structure: a network of connected pentasil units related to the layer of RUB-18 and a bidimensional checkerboard of intersecting ladders of 4-membered rings. The two configurations are related by the simple face-sharing inversion of a hydroxyl-bearing tetrahedron. (C) 2014 Elsevier Inc. All rights reserved.
