Scheme 1From: Investigation of supramolecular synthons and structural characterisation of aminopyridine-carboxylic acid derivativesThree types of supramolecular synthons, (A), (B) and (C), were discussed in this paper. (A) & (B) represent homo and heterosynthons, R 2 2 8 , respectively whereas (C) represents a DADA array, R 2 3 8 : R 2 2 8 : R 2 3 8 .Back to article page
