“…N2-C3 and N6-C9, are significantly shorter than the N4-C5 bond in the neutral thiazole ring (Table 1). This is consistent with the DABT salts reported previously (Liu & Xu, 2005;Liu et al, 2002;Liu, Xu & Sun, 2003).…”

The crystal structure of the title compound, C6H8N4S22+·2C6H7N4S2+·4C7H4NO4−, comprises diprotonated diaminobithiazole (DABT) dications located on inversion centers, monoprotonated DABT cations and nitrobenzoate anions. The relatively short C—N(amino) bond distances, ranging from 1.310 (2) to 1.350 (2) Å, indicate electron delocalization between the amino groups and thiazole rings. Intermolecular N—H⋯O and N—H⋯N hydrogen bonds stabilize the crystal packing.

“…B1A3 crystallizes out in the noncentrosymmetric monoclinic space group P2 1 (Figure 3). We would like to mention that similar O•••S interactions were found in the series of amidothiazole gelator 14 and most of the known 2aminothiazole salts/cocrystals [21][22][23][24][25][26][27][28][29]31 (Supporting Information, Table S1) ) interactions between the thiazole ring hydrogen and hydroxyl oxygen of acid. Interestingly, the methyl proton of 2-amino-4-methylthiazole is found not interacting with any neighboring atoms (Figure 7).…”

Crystal engineering and supramolecular synthons approach are applied to synthesize a series of 2aminothiazole (and its methyl derivatives) salts/cocrystals with various dicarboxylic acids. On the basis of combinatorial library approach, 24 new salts/cocrystals of 2-aminothiazole and its methyl derivatives with various dicarboxylic acid (aliphatic unsaturated and saturated backbone) were synthesized and characterized. All the synthesized salts were subjected to gelation test in various solvents (polar and nonpolar). Interestingly, one of the salts/cocrystals, i.e., B3A6 (5methyl-2-aminothiazolium hydrogen decandioate) was found to be capable of immobilizing water at slightly higher minimum gelator concentration (MGC). A structure−property correlation between various cocrystals/salts based on single crystal X-structure of 11 compounds was undertaken. The gelation property of 2-aminothiazole-based gelling agent was found to be governed by the position of a methyl group on the thiazole ring, a length of the aliphatic carbon chain of dicarboxylic acid, and formation of hydrogen bonded network (HBN) leading to void in the single crystal structure. The comparison of single crystal X-ray structures of nongelators and a gelator were undertaken to understand the probable mechanism of hydrogelation in the series of 2-aminothiazole-based salts/cocrystals.

“…It was found that polymers containing bithiazole rings are good ligands because the two nitrogen atoms in the bithiazole rings are able to chelate metal ions to form a stable five-member ring. The crystal structure of metal complexes of the monomer, 2,2 0 -diamino-4,4 0 -bithiazole (DABT) has been characterized by X-ray diffraction [6,7]. In 2000, three poly(Schiff base)-Fe 2þ complexes containing bithiazole rings were prepared for the first time and found to be soft ferromagnets [8].…”
