2-Benzoyl-1-tert-butyl-2-(1,2-di­benzoyl-2-tert-butyl­hydrazinosulfanyl)-1-(3,5-di­methyl­benzoyl)­hydrazine

The crystal structure of the title compound, C₃₈H₄₂N₄O₄S, an insect-growth regulator, has been determined. The two tert-butyl groups are in different environments and this is reflected in the ¹H NMR spectrum.

1-tert-Butyl-2-(4-ethyl­benzoyl)-1-(2-mercapto-3,5-di­methyl­benzoyl)­hydrazine

In the title compound, C₂₂H₂₈N₂O₂S, the carbonyl group closer to the thiol group is almost perpendicular to the attached benzene ring. The crystal packing is stabilized by intermolecular N—H...O and C—H...O hydrogen bonds.

Diaquadiperchlorato[μ-11,23-dimethyl-3,7,15,19-tetraazatricyclo[19.3.1.1^9,13]hexacosa-1(25),2,7,9,11,13(26),14,19,21,23-decaene-25,26-diolato-1κ²N,N′;2κ²N′′,N′′′;1:2κ²O:O′]dicadmium(II) diaqua[μ-11,23-dimethyl-3,7,15,19-tetraazatricyclo[19.3.1.1^9,13]hexacosa-1(25),2,7,9,11,13(26),14,19,21,23-decaene-25,26-diolato-1κ²N,N′;2κ²N′′,N′′′;1:2κ²O:O′]dicadmium(II) diperchlorate

In the title complex, [Cd₂(C₂₄H₂₆N₄O₂)(ClO₄)₂(H₂O)₂][Cd₂(C₂₄H₂₆N₄O₂)(H₂O)₂](ClO₄)₂, the two distinct macrocycles adopt essentially flat structures. They each encapsulate two Cd atoms. One Cd coordination polyhedron, completed by a water O atom and a perchlorate O atom, is distorted octa­hedral, while the other is best described as a CdN₂O₃ square-based pyramid, with water in the apical site. Both dinuclear complexes are centrosymmetric.

Bis­[μ-4-fluoro-6-hydroxymethyl-2-(2,5,8-triaza­oct-1-enyl)phenolato]dicopper(II) bis(perchlorate) methanol solvate

The title dinuclear complex, [Cu₂(C₁₂H₁₇FN₃O₂)₂](ClO₄)₂·CH₄O, was synthesized by condensation between diethyl­ene­triamine and 2-form­yl-4-fluoro-6-hydroxy­methyl­phenol in the presence of copper(II). It contains two similar units, which are linked by Cu—O bonds. The approximate planes of the two units are parallel to each other, and π–π inter­action exists between the two units.
