An investigation of supramolecular synthons in 1,2,4-triazole-3(4H)-thione compounds. X-ray crystal structures, energetic and Hirshfeld surface analysis
(Elsevier Science, 2019-11)
A series of four closely related 1,2,4-triazole-3-thione (1-4) compounds was obtained by heterocyclization of thiosemicarbazides under basic catalytic conditions. The crystal structures of the 4-alkyl-5-(substituted-phen ...

(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2013-03-08)
This study shows the triazenes ligands and complexes Pd(II), K+ and Au(I) obtained from reactions of the ligands with fragments para-sulfonamidephenyl, comprising triazene ligand 1,3-bis (4 - sulfonamidephenyl) (1) and the ...
Co-crystals of non-steroidal anti-inflammatory drugs (NSAIDs): Insight toward formation, methods, and drug enhancement
(2021-10-01)
Pharmaceutical co-crystals have been explored by many researchers as a strategy to optimize physicochemical properties of solid-state drugs. Their improvements of solubility, bioavailability, and the reduced tendency for ...
Synthesis, characterization and solubility of a new anthelmintic salt: Mebendazole nitrate
(Elsevier Science, 2018-06)
Salt formation approach was taken to improve Mebendazole (MBZ) solubility. MBZ polymorph A was easily recrystallized as a 1:1 nitrate salt (MBZ N) in methanol. Single crystal X-ray diffraction data show that MBZ N crystallizes ...
The relevance of the fluorine interactions in the supramolecular structure of a complex constructed from copper(II) hexafluoroacetylacetonate and the 40-(3-pyridyl)-2,20:60,200-terpyridine ligand. Novel C–F/p synthons involving the p-system of the terpyridine moieties and those of the hexafluoroacetylacetonate chelate rings
(ELSEVIER, 2010)
Reaction of 40-(3-pyridyl)-2,20:60,200-terpyridine (pyterpy) with Cu(hfacac)2 (hfacac = hexafluoroacetylacetonate)
led to the formation of the novel compound [Cu3(hfacac)4(m-pyterpy)2][Cu(hfacac)3]2 (1).
The structure ...
Supramolecular self-assembly of a coumarine-based acylthiourea synthon directed by π-stacking interactions: Crystal structure and Hirshfeld surface analysis
(Elsevier Science, 2016-05)
The structure of 1-(2-oxo-2H-chromene-3-carbonyl)-3-(2-methoxy-phenyl)thiourea (1) has been determined by single-crystal X-ray crystallography. This compound crystallizes in the monoclinic space group P21/c with a = 7.455 ...
