Thermodynamic Properties of 4'-Demethylepipodophyllotoxin in Dimethyl Sulfoxide

Bis[4-(4-chloro­phen­yl)-4-hydroxy­piperidinium] dipicrate dimethyl sulfoxide solvate

The asymmetric unit of the title salt solvate, 2C(11)H(15)ClNO(+)·2C(6)H(2)N(3)O(7) (-)·C(2)H(6)OS, contains two crystallographically independent 4-(4-chloro-phen-yl)-4-hydroxy-piperidinium cations, two picrate anions and a dimethyl sulfoxide solvent mol-ecule. In each cation, the piperidinium ring adopts a chair conformation. In the crystal structure, the cations, anions and solvent mol-ecules...

DFT study of dimers of dimethyl sulfoxide in gas phase

Density functional (DFT) calculations at M05-2x/aug-cc-pVDZ level were used to analyze the interactions between dimethyl sulfoxide (DMSO) dimers. The structures obtained have been analyzed with the Atoms in Molecules (AIMs) and Natural Bond Orbital (NBO) methodologies. Four minima were located on the potential energy surface of the dimers. Three types of interactions are observed, CH•••O, CH•••...

Bis(μ-4-nitro-2-{[2-(oxidometh­yl)phen­yl]imino­meth­yl}phenolato)bis­[chlorido(dimethyl sulfoxide)­iron(III)] dimethyl sulfoxide disolvate

In the centrosymmetric dimeric title complex, [Fe(2)(C(14)H(10)N(2)O(4))(2)Cl(2)(C(2)H(6)OS)(2)]·2C(2)H(6)OS, two {Fe(L)Cl(DMSO)} units (L is the tridentate ligand 4-nitro-2-{[2-(oxidometh-yl)phen-yl]imino-meth-yl}phenolate; DMSO is dimethyl sulfoxide) are bridged by two O atoms, with an Fe⋯Fe separation of 3.1838 (8) Å. The coordination polyhedron of the Fe(III) atoms can be described as disto...

Pyrimethaminium 2-{[4-(tri­fluoro­meth­yl)phen­yl]sulfan­yl}benzoate dimethyl sulfoxide monosolvate

In the cation of the title solvated mol-ecular salt, C12H14ClN4 (+)·C14H8F3O2S(-)·C2H6OS [systematic name of the cation: 2,4-di-amino-5-(4-chloro-phen-yl)-6-ethyl-pyrimidin-1-ium], the dihedral angle between the planes of the pyrimidinium and 4-chloro-phenyl rings is 77.2 (5)°. In the anion, the planes of the benzene rings are twisted with respect to each other by 71.5 (5)°. Disorder was modell...
