Two N-{[4-(3-aryl-4-sydnonylideneamino)-5-sulfanylidene-1H-1,2,4-triazol-3-yl]methyl}benzamides as disordered ethanol monosolvates
Abstract
Two new N-{[4-(3-aryl-4-sydnonylideneamino)-5-sulfanylidene-1H-1,2,4-triazol-3-yl]methyl}benzamides have been prepared by acid-promoted condensation reactions between 3-aryl-4-formylsydnones and N-[(4-amino-5-sulfanylidene-1H-1,2,4-triazol-3-yl)methyl]benzamide, and both have been crystallized as ethanol monosolvates. N-{[4-(3-Phenyl-4-sydnonylideneamino)-5-sulfanylidene-1H-1,2,4-triazol-3-yl]methyl}benzamide ethanol monosolvate, C19H15N7O3S·C2H6O ( I ), and N-({4-[3-(4-methylphenyl)-4-sydnonylideneamino]-5-sulfanylidene-1H-1,2,4-triazol-3-yl}methyl)benzamide ethanol monosolvate, C20H17N7O3S·C2H6O ( II ), differ only in the presence of a methyl group for ( II ) instead of a hydrogen atom for ( I ), and in both of them the ethanol component is disordered over two sets of atomic sites having occupancies of 0.836 (6) and 0.164 (6) in ( I ), and 0.906 (6) and 0.094 (6) in ( II ). Combinations of O—H⋯O and N—H⋯O hydrogen bonds link the molecules into cyclic, centrosymmetric four-molecule aggregates. Comparisons are made with the structures of some related compounds.
