Abstract: The results of the X-ray structure analysis of three novel 3,6-bis(pyridin-2-yl)-1,2,4,5-tetrazine cocrystals are presented. These are 3,6-bis(pyridin-2-yl)-1,2,4,5-tetrazine-2,4,6-tribromophenol (1/2), C12H8N6·2C6H3Br3O, 3,6-bis(pyridin-2-yl)-1,2,4,5-tetrazine-isonicotinic acid N-oxide (1/2), C12H8N6·2C6H5NO3, and 3,6-bis(pyridin-2-yl)-1,2,4,5-tetrazine-4-nitrobenzenesulfonamide (1/1), C12H8N6·C6H6N2O4S. Special attention is paid to a conformational… read more here.
