Crystals of the title compound, C(12)H(14)N(4)S, were obtained from a condensation reaction of 4-amino-3-ethyl-1H-1,2,4-triazole-5(4H)-thione and 2-methyl-benzaldehyde. In the mol-ecular structure, there is a short N=C double bond [1.255 (2) Å], and the benzene and triazole rings are located on opposite sites of this double bond. The two rings are approximately parallel to each other, the dihed...

The title compound, [Fe(2)(C(5)H(5))(2)(C(30)H(22)N(2)O(2))], a 2:1 product of the reaction of 2-ferrocenylbenzoic acid and 2-amino-4-methyl-pyridine, forms a twisted mol-ecular structure in the solid state due to steric effects from the two benzene rings ortho-substituted with ferrocenyl and carbonyl-derived groups. A short intra-molecular C-H⋯π interaction is observed involving a substituted ...

The yeast Yarrowia lipolytica is well known for its versatile production of metabolites from various substrates, but, although isolated from, e.g., wild-fermented Belgian Sour beers, it rarely considered a starter culture in fermented beverages. In this study, we aimed to elucidate the ability Y. ferment brewers’ wort containing iso-α-acid 7 days at low and high aeration 20 °C 30 °C, with speci...

In the present study, new Schiff's base derivatives: (Z)-4-amino-5-(2-(3- fluorobenzylidene)hydrazinyl)-4H-1,2,4-triazole-3-thiol (Y1), (Z)-3-((2-(4-amino-5- mercapto-4H-1,2,4-triazol-3-yl)hydrazono)methyl)phenol (Y2), (Z)-2-((2-(4-amino-5- mercapto-4H-1,2,4-triazol-3-yl)hydrazono)methyl)phenol (Y3) and 3-((Z)-(2-(4- (((E)-3-hydroxybenzylidene)amino)-5-mercapto-4H-1,2,4-triazol-3-yl)hydrazono)m...

In the asymmetric unit of the title salt, C6H9N2 (+)·C7H7O3S(-), there are two independent 2-amino-6-methyl-pyridinium cations and two independent 4-methyl-benzene-sulfonate anions. Both cations are protonated at their pyridine N atoms and their geometries reveal amine-imine tautomerism. In the 4-methyl-benzene-sulfonate anions, the carboxyl-ate groups are twisted out of the benzene ring planes...

Mononuclear Ru(III) complexes of the type [Ru(LL)Cl2(H2O)] (LL = monobasic tridentate Schiff base anion: (1Z)-N'-(2-{(E)-[1-(2,4-dihydroxyphenyl)ethylidene]amino}ethyl)-N-phenylethanimidamide [DAE], 4-[(1E)-N-{2-[(Z)-(4-hydroxy-3-methoxybenzylidene)amino]ethyl}ethanimidoyl]benzene-1,3-diol [HME], 4-[(1E)-N-{2-[(Z)-(3,4-dimethoxybenzylidene)amino]ethyl}ethanimidoyl]benzene-1,3-diol [MBE], and N-...

The asymmetric unit of the title compound, C(18)H(23)N(2) (+)·C(6)H(5)O(3)S(-)·H(2)O, comprises a 2-[4-(diethyl-amino)-styr-yl]-1-methyl-pyridinium cation, a benzene-sulfonate anion and a solvent water mol-ecule. One ethyl substituent of the diethyl-amino group of the cation is disordered over two positions in a 0.73789 (9):0.26211 (9) ratio. The cation exists in the E configuration with respec...

The asymmetric unit of the title compound, C(11)H(14)N(2)O(4), comprises four crystallographically independent mol-ecules (A, B, C and D) with similar geometries. In each mol-ecule, the butyl-amino side chain is in an extended conformation, and the carboxyl and butyl-amino groups are almost coplanar with the attached benzene ring; the nitro group is slightly twisted away from the benzene ring. ...

In the title compound, C(11)H(11)ClN(4)O(3)S, the S atom is bonded in a distorted tetra-hedral geometry, by two O atoms, a C atom of the benzene ring and an amino N atom. The essentially planar pyrimidine ring [maximum deviation = 0.020 (1) Å] forms a dihedral angle of 87.57 (5)° with the benzene ring. In the crystal structure, pairs of mol-ecules are linked by inter-molecular N-H⋯O hydrogen bo...
