Abstract

BEDT-TTF forms three packing arrangement styles in its radical cation salts with [Cr(NCS)(6)](3-) in two of which two trans-oriented isothiocyanate ligands penetrate the BEDT-TTF layers either at the point where a solvent (nitrobenzene) is incorporated in a stack of donors or by four donor molecules forming a "tube" motif to accept a ligand at each end along with a small solvent molecule in between (acetonitrile). The [Cr(NCS)(5)NH3](2-) ion forms a related crystal packing arrangement with BEDT-TTF with a reduction in the number of "tube" motifs needed to accept an isothiocyanate ligand. (C) 2015 The Authors.
