چکیده

THE TITLE COMPOUND (SYSTEMATIC NAME 5,6β-dihy-droxy-1α,14α,16β-trimeth-oxy-4-methyl-7β,8-methyl-enedi-oxy-20-ethyl-aconitan-6-yl acetate acetone monosolvate), C(27)H(41)NO(8)·C(3)H(6)O, was isolated from Delphinium bonvalotii Franch, and is a typical C(19)-diterpenoid alkaloid. The mol-ecule has a lycoctonine carbon skeleton with four six-membered rings and three five-membered rings. Three six-membered rings adopt the chair conformations while the fourth adopts a boat conformation, while the five-membered rings have the envelope conformations. The solvent mol-ecule links with the organic mol-ecule via a classical O-H⋯O hydrogen bond. Weak C-H⋯O hydrogen bonding is present in the structure. An intra-molecular O-H⋯O hydrogen bond also occurs.

{μ-6,6′-Dimeth­oxy-2,2′-[propane-1,3-diylbis(nitrilo­methyl­idyne)]­diphenolato}­trinitratocopper(II)lutetium(III) acetone solvate

In the title complex, [CuLu(C(19)H(20)N(2)O(4))(NO(3))(3)]·CH(3)COCH(3), the Cu(II) ion is four-coordinated in a square-planar geometry by two O atoms and two N atoms from the deprotonated Schiff base. The Lu(III) ion is ten-coordinate, chelated by three nitrate groups and linked to the four O atoms of the deprotonated Schiff base. A mol-ecule of acetone is present as a solvate.

Characterisation and evaluation of pharmaceutical solvates of Atorvastatin calcium by thermoanalytical and spectroscopic studies

UNLABELLED BACKGROUND Atorvastatin calcium (ATC), an anti-lipid biopharmaceutical class II drug, is widely prescribed as a cholesterol-lowering agent and is presently the world's best-selling medicine. A large number of crystalline forms of ATC have been published in patents. A variety of solid forms may give rise to different physical properties. Therefore, the discovery of new forms of thi...

The Role of Coulomb Interactions for Spin Crossover Behaviors and Crystal Structural Transformation in Novel Anionic Fe(III) Complexes from a -Extended ONO Ligand

To investigate the π-extension effect on an unusual negative-charged spin crossover (SCO) FeIII complex with a weak N2O4 first coordination sphere, we designed and synthesized a series of anionic FeIII complexes from a π-extended naphthalene derivative ligand. Acetonitrile-solvate tetramethylammonium (TMA) salt 1 exhibited an SCO conversion, while acetone-solvate TMA salt 2 was in a high-spin s...

A new solvate of epalerstat, a drug for diabetic neuropathy

Epalerstat {systematic name: (5Z)-5-[(2E)-2-methyl-3-phenyl-prop-2-en-1-yl-idene]-4-oxo-2-sulfanyl-idene-1,3-thia-zolidine-3-acetic acid} crystallized as an acetone monosolvate, C15H13NO3S2·C3H6O. In the epalerstat mol-ecule, the methyl-propyl-enediene moiety is inclined to the phenyl ring and the five-membered rhodamine ring by 21.4 (4) and 4.7 (4)°, respectively. In addition, the acetic acid ...
