Molecular recognition: Chain length selectivity studies of dicarboxylic acids by the cavity of a new Troger's base receptor

2-Amino-4-methylpyrimidine: A simple supramolecular scaffold for carboxylic acid complexes both in solid and solution states

“…A single molecule of 2-aminopyrimidine has two equivalent proton donors and acceptors available for hydrogen bonding to neighboring molecules, which are complementary to carboxylic acids. Several dicarboxylic acids [14][15][16] form 1:1 and 1:2 complexes with 2-aminopyrimidine, the crystal structures of which clearly illustrate the formation of cyclic hydrogen bonded [17,18] complexes R 2 2 (8). Another factor can play a role in the solid-state structure of co-crystals of 2-aminopyrimidine ring system and dicarboxylic acids.…”

Synthesis, crystal growth and characterization of an organic material: 2-Aminopyridinium succinate succinic acid single crystal

“…However, organic crystals have relatively weak intermolecular bindings and it is too difficult to grow high quality large size crystals compared with inorganic crystals. Hydrogen bonding plays a key role in molecular recognition [9] and crystal engineering research [10].…”

Theoretical investigation of some specific features of the electronic structure and optical properties of Benzoic Acid 2-Amino-4,6-Dimethylpyrimidine (1:1) co-crystals

“…Benzoic Acid 2-Amino-4,6-Dimethylpyrimidine (1:1) is one of the co-crystals, in which the hydrogen bond interactions play an important role in composing the structure, etc. [2,3]. Therefore, it is necessary to investigate the hydrogen-bonded networks which are linked with mobile protons.…”
