Figure 17From: Design of co-crystals/salts of some Nitrogenous bases and some derivatives of thiophene carboxylic acids through a combination of hydrogen and halogen bonds(a) A portion of the crystal packing of 14b showing hydrogen-bonding patterns with graph-set notations R 3 2(9), R 2 2(8). Dotted lines denote hydrogen bonds. H atoms non-involved in hydrogen-bonding omitted for clarity. (b) Hydrogen bonded network formed in (14b).Back to article page
