Decacarbon­yl(μ-ethyl­idenimino-1κN:2κC)-μ-hydrido-triangulo-triosmium(3 Os–Os)

The crystal structure of a new triosmium carbonyl complex containing bridging ethyl­idenimino and hydrido ligands is reported. A relatively high-yield synthesis was accomplished with the use of a triazine starting material and microwave heating.

Bis[2-(di­methyl­amino-κN)-α,α-di­phenyl­benzene­methano­lato-κO](tetra­hydro­furan-κO)magnesium(II)

Isolated mol­ecules are present in the crystal structure of the title complex, exhibiting a distorted square-pyramidal coordination sphere around the central Mg^II atom. The O atom of the tetra­hydro­furan mol­ecule occupies the apical position.

3-Bromo­pyridine-2-carbo­nitrile

The crystal structure of the title compound, also known as 3-bromo­picolino­nitrile, synthesized by cyanation of 2,3-di­bromo­pyridine, is described.

3,3′-[(1E,1′E)-Hydrazine-1,2-diylidenebis(ethan-1-yl-1-yl­idene)]bis­(4-hy­droxy-6-methyl-2H-pyran-2-one)

The title mol­ecule lies about an inversion centre at the mid-point of the N—N bond and features two intra­molecular O—H⋯N and two C—H⋯O hydrogen bonds, each of which forms an S(6) ring motif. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds into infinite zigzag chains propagating along the c-axis direction. π–π stacking inter­actions between the pyrone rings stack the mol­ecules along b.

4-Amino-5-{[cyclo­hex­yl(meth­yl)amino]­meth­yl}iso­phthalo­nitrile

In the crystal structure of 4-amino-5-{[cyclo­hex­yl(meth­yl)amino]­meth­yl}isophthalo­nitrile, inter­molecular N—H⋯N hydrogen-bond inter­actions are observed.

1-Iso­butyl-8,9-dimeth­oxy-3-phenyl-5,6-dihidro­imidazo[5,1-a]isoquinolin-2-ium chloride

The title compound was synthesized by condensation and cyclization of α-benzoyl­amino-γ-methyl-N-[2-(3,4-di­meth­oxy­phen­yl)eth­yl]valeramide in the presence of phosphoryl chloride (Bischler–Napieralski reaction).

9α-Hy­droxy-4,8-di­methyl-3′-phenyl-3,14-dioxatri­cyclo­[9.3.0.0^2,4]tetra­dec-7-en-13-one-12-spiro-5′-isoxazole monohydrate

The synthesis of a new spiro-isoxazoline by 1,3-dipolar cyclo­addition is reported.

2,4-Di­chloro-6-[(2-hy­droxy-5-methyl­anilino)methyl­idene]cyclo­hexa-2,4-dienone

The structure of 2,4-di­chloro-6-[(2-hy­droxy-5-methyl­anilino)methyl­idene]cyclo­hexa-2,4-dienone is reported.
