Specificity in Crystal Engineering: Polymerisation and Dimerisation Motif Design in Pyridine System

2-Amino-6-hydroxymethylpyridine (1) and 2-pivaloylamino-6-hydroxymethylpyridine (2) are important hydrogen bonding synthons as they are the very useful substrates which can be used for the synthesis of designed receptors in the field of molecular recognition [1] and supramolecular chemistry [2]. Here we report the compounds 1 and 2 as simple designers to create polymeric supramolecular three-dimensional assembly and self-complementary dimer respectively in solid-state crystal engineering.
