NLO crystals of bis[1-(diaminomethylene)thiouron-1-ium] tartate(2−) hemihydrate and deuterated [1-(diaminomethylene)thiouron-1-ium] tartate(−)

“…4). The presence of the sulphur atom in the 1-(diaminomethylene)thiouron-1-ium cation raises the question of whether there are hydrogen bonds with the S as an acceptor, although the importance of such interactions has been questioned [30]. Nevertheless, there are authors motivated by the high content of sulphur in biological systems who claim to utilise the DAHÁ Á ÁS interactions (D = donor) in the crystal engineering.…”

“…3a). The importance of such interactions has been questioned [20]. However, the DAHÁ Á ÁS interactions (D = donor) are important in the biological systems due to presence of high content of S atom in biological molecules.…”

Supramolecular hydrogen-bonding networks in the 1-(diaminomethylenene)thiouron-1-ium 4-hydroxybenzoate, 3,4-dihydroxybenzoate and 3,4,5-trihydroxybenzoate monohydrate crystals

“…The 1-(diaminomethylene)thiouron-1-ium cation contains the sulphur atom that can form hydrogen bonds as an acceptor, although the importance of such interactions has been questioned [23]. However, the DAHÁ Á ÁS interactions (D = donor) are important in the biological systems due to presence of high content of S atom in biological molecules.…”
