    Notes: A series of derivatives of 3-amino-2-oxazolidinone have been prepared. The title derivative, C15H19ClN3O3+·Cl−·H2O, is a potential psychotropic drug. The structure is assembled by strong and weak hydrogen bonds into a three-dimensional infinite framework. In the structure, intramolecular hydrogen bonds link C and O atoms to create a fused three-membered ring system.

    Notes: The structure of the title compound, C9H18N2O2, has been determined. The morpholine ring exists in an almost ideal chair conformation. The central part of the molecule is almost ideally planar. The molecule is stabilized by weak C—H...N and C—H...O hydrogen bonds. Molecules of the title compound associate via N—H...O and C—H...O interactions to form a linear hydrogen-bonded chain along the z axis.

    Polymorphic form of 1,3,5-tris[(diphenylphosphine oxide)methyl]benzene acetonitrile solvate monohydrate (2001)

    Notes: The title compound, benzene-1,3,5-triyltrismethylenetris(diphenylphosphine oxide) acetonitrile solvate monohydrate, C45H39O3P3·C2H3N·H2O, forms two polymorphs: (I), which crystallizes in the triclinic space group P1, and (II), which crystallizes in the monoclinic space group Pn. The crystal and molecular structures of (I) were previously determined. The results of the crystal structure determination of (II) are presented here. The overall arrangement of two of the diphenylphosphine oxide substituents is determined by strong hydrogen bonds Owater—H...Ooxide. All three P atoms adopt distorted tetrahedral geometry, with C—P—C angles equal to or smaller than tetrahedral and O—P—C angles greater than tetrahedral. All three diphenylphosphine oxide substituents are stabilized by weak Cphenyl—H...Ooxide hydrogen bonds. For each substituent, one of the phenyl rings is almost coplanar with the P=O bond.

    Notes: All interatomic distances of the title compound, C5H12N+·Cl−, are normal. All C atoms lie in a common plane. Molecules of the title compound are assembled by intermolecular weak N—H...Cl hydrogen bonds into an infinite zigzag ribbon structure along the y axis. The ribbon is bent repeatedly with angles of 34.15 (6)°.

    Notes: The Mn atom in the title compound, [MnCl2(C10H8N2)2(H2O)2], occupies a centre of symmetry. The pyridine rings are planar and all bond distances are normal. Bond-valence calculations show that the Mn—O bond is weaker than both the Mn—N and Mn—Cl bonds. The molecules are held together in the crystal by hydrogen bonds.

    Notes: All interatomic distances in the title compound, C28H34N4O4, are normal. The (4-ethoxyphenyl)amino parts of the side branches are almost ideally planar. The overall arrangement of the side branches seems to be imposed by hydrogen bonds. The substituents are stabilized by interbranch N—H...O hydrogen bonds. The structure of the title compound is assembled by intermolecular N—H...O hydrogen bonds, forming a two-dimensional framework.

    Notes: A series of derivatives of 3-amino-2-oxazolidinone have been prepared. The 5-morpholinomethyl-3-(4-chlorobenzylideneamino)-2-oxazolidinone derivative is a potential psychotropic drug. Preliminary clinical data showed that the compound exhibits antidepressive activity in humans. The molecular geometry of the title compound, C15H19FN3O3+·Cl−·H2O, is similar to that of 5-morpholinomethyl-3-(4-chlorobenzylideneamino)-2-oxazolidinone. The oxazolidinone ring exists in an almost ideal half-chair conformation. The primary location of molecular interaction with an acid residue within a putative receptor site is at the morpholine N atom. The structure of the title compound is built up from strong and weak intermolecular hydrogen bonds forming a two dimensional infinite hydrogen-bond network.

Preliminary clinical data showed that the compound exhibits antidepressive activity in humans. The molecular geometry of the title compound, C15H18FN3O3, is similar to 5-morpholinomethyl-3-(4-chlorobenzylideneamino)-2-oxazolidinone. Two atoms of the title compound are disordered so that two different conformations of the oxazolidinone ring were found; one is a twist and the other is an envelope conformation. The crystal structure of title compound is formed by weak intermolecular C—H...O hydrogen bonds resulting in a two-dimensional infinite hydrogen-bond network.
