The complex resulting from the reaction of L-threonine with cadmium acetate dihydrate is a polymeric system with the carboxyl­ate group of L-threonine bridging symmetry-related Cd^II centres in the crystal.

Polar crystal of vanillylformamide through replacement of the alkene by an isosteric formamide group

A novel polar crystal of vanillylformamide (a eugenol isostere) was prepared and characterized.

Methyl 1-methyl-1H-indole-3-carboxyl­ate

In the crystal structure of this indole derivative, mol­ecules form three kinds of inter­molecular C—H⋯O hydrogen bonds, resulting in a sheet structure in the ab plane. Parallel sheets inter­act by C—H⋯π stacking, stabilizing the crystal packing.

4-Methyl-1H-1,5-benzodiazepin-2(3H)-one

In the title compound, the seven-membered heterocycle displays a half-chair conformation. In the crystal, N—H⋯O and C—H⋯O hydrogen bonds form [100] chains.

2,4-Di­chloro-N-(2,5-dioxopyrrolidin-1-yl)benzamide

In the title compound, pyrrolidine and benzene rings make a dihedral angle of 52.9 (2)°. In the crystal, mol­ecules are linked via N—H⋯O hydrogen bonds, forming chains along the b-axis direction. π–π inter­actions link these chains into a two-dimensional network parallel to (100).

4-Methyl­anilinium 2-carboxyacetate

In the crystal of the title salt, the cations are linked to the anions via N—H⋯O and trifurcated N—H⋯(O,O,O) hydrogen bonds. The anions are linked into [010] chains by O—H⋯O hydrogen bonds. Taken together, these interactions generate (100) sheets.

1-Di­phenyl­phosphanyl-2-(di­phenyl­phosphor­yl)hydrazine

The title compound is an asymmetrically substituted hydrazine derivative bearing a phosphoryl and a phosphanyl substituent.

1-Methyl-1H-imidazol-3-ium methane­sulfonate

The structure of the title salt has monoclinic (P2₁/n) symmetry. The 1-methyl­imidazolium cation and the methyl­sulfonate anion in the asymmetric unit are held together by a strong N—H⋯O hydrogen bond.

Crystal structure of the ethyl 2,4-dihy­droxy-6-methyl­benzoate from Illicium difengpi K.I.B et K.I.M.

In the crystal, the compound forms offset slanted stacks of alternating inversion-related mol­ecules along the a-axis direction. Inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into double strands parallel to the [101] direction.
