Abstract
This paper reports synthesis, characterization and theoretical studies of two 1:1 stoichiometric ratio cocrystals of 4,4′-bithiazole-2,2′-diamine (DABTZ) with 2,5-bis(4-pyridyl)-1,3,4-oxadiazole (bpo) and 1,3-bis(4-pyridyl)ethane (bpa). These cocrystal compounds have been prepared by slow evaporation method and characterized by elemental and thermal analysis, FTIR, 1H and 13C-NMR spectroscopies and X-ray crystallography. X-ray crystal analyses show that these structures [(DABTZ) (bpo)] and [(DABTZ) (bpa)] have crystallized in monoclinic forms with space groups of P2 1/n and C 2/c, respectively. These structures were studied theoretically and the results are in good agreement with the experimental data.
