Crystal structure of the Al₂₀Mn_5.37Ni_1.31 phase in the Al–Mn–Ni system

The phase Al₂₀Mn_5.37Ni_1.31 in the ternary system Al–Mn–Ni system was synthesized by high-temperature sinter­ing and its crystal structure has been refined from single-crystal X-ray data.

The structure of the aluminium-abundant γ-brass-type Al_8.6Mn_4.4

An aluminium-abundant γ-brass phase, Al_8.6Mn_4.4, was synthesized by high-temperature sinter­ing, and its single-crystal structure has been determined.

Tetra­ammonium μ-ethyl­enedi­amine­tetra­acetato-1κ³O,N,O′:2κ³O′′,N′,O′′′-bis­[trioxidotungstate(VI)] tetra­hydrate

The title compound, (NH₄)₄[W₂(C₁₀H₁₂N₂O₈)O₆]·4H₂O, is a binuclear complex of tungsten with the edta⁴⁻ ligand bridging two WO₃ units, leading to a distorted octa­hedral coordination environment for the tungsten atoms. The supra­molecular crystal structure is built up by the anion, four ammonium cations and four solvent water mol­ecules and is established via hydrogen bonds of the N—H⋯O and O—H⋯O type.

(E)-Benzyl 2-{4-[eth­yl(2-hy­droxy­eth­yl)amino]­benzyl­idene}hydrazinecarbodi­thio­ate

In the title compound, mol­ecules are linked into chains by O—H⋯S and N—H⋯O hydrogen bonds.

(2R,4S,5S)-5-Meth­oxy-4-methyl-3-oxohept-6-en-2-yl benzoate

The title compound was synthesized in the course of the total synthesis of fusaequisin A in order to verify and confirm the configurations of the stereogenic centers and to exclude the possibility of epimerization during the methyl­ation process. The absolute configuration was determined by anomalous dispersion and agrees with the configuration of the allylic alcohol used in the synthesis.

Ethyl 2-[(E)-({2,4-dimeth­oxy-6-[2-(4-meth­oxy­phen­yl)ethen­yl]benzyl­idene}amino)­oxy]acetate

The crystal structure of a resveratrol–oxime ester is reported.

(3E)-4-[(Naphthalen-1-yl)amino]­pent-3-en-2-one hemihydrate

In the title compound, the dihedral angle between the naphthalene ring system and the amino­pentenone fragment mean plane (C=C—N—C=O) is 76.91 (19)°. In the crystal, a water mol­ecules are connected with the N-naphthyl­pent-3-en-2-one mol­ecules by O—H⋯O-type hydrogen bonds.
