Supramolecular synthons in the co-crystal structures of 2-aminopyrimidine with diols and carboxylic acids

The co-crystal structures of 2-aminopyrimidine (APY) with diols have been analysed and poly-component hydrogen bond arrangements have been found. In addition, a novel supramolecular synthon has been identified and rationalised in the co-crystal structure of APY and 1,4-naphthalenedicarboxylic acid (NDA).
