Spectroscopic, thermal and structural studies of cocrystal of 2,2′-diamino-4,4′-bis(1,3-thiazole) with 4,4′-bipyridine, 1,2-bis(4-pyridyl)ethylene and 1,3-bis(4-pyridyl) propane

Three new cocrystals based upon 2,2'-diamino-4,4'-bis(1,3-thiazole) (DABTZ) with 4,4'-bipyridine (4,4'-bipy), 1,2-bis(4-pyridyl)ethylene (bpe) and 1,3-bis(4-pyridyl)propane (bpp): [(DABTZ) (4,4'-bipy)], [(DABTZ) (bpe)] and [(DABTZ) (bpp)] have been synthesized and characterized by elemental analysis, IR-, H-1 NMR-, C-13 NMR spectroscopy and studied by thermal and X-ray crystallography. Selfassembly of these compounds in the solid state is likely caused by both hydrogen bonding, and pi-pi stacking. (c) 2006 Elsevier B.V. All rights reserved.
