Synthesis and solid state self-assembly of an isatin-thiazoline hybrid driven by three self-complementary dimeric motifs

An interesting isatin-thiazoline hybrid molecule having C=N-N=N bonds has been synthesized and its solid state self-assembly behaviour was studied by X-ray diffraction technique. A layered structure based on hexameric supracycles, which are formed through three different self-complementary dimeric motifs, was obtained. The supramolecular forces involved in the stabilization of this structure are NH-O, CH-O, CH-N, CH-pi, pi-pi, CH-Cl and unconventional N-O interactions. (C) 2014 Elsevier Ltd. All rights reserved.
