N hydrogen bonds help to consolidate the crystal packing.
Intermolecular hydrogen bonds between amide N and amide O atoms of
neighbouring molecules allow the construction of a two-dimensional
network.
O hydrogen bonds may be effective in the stabilization of the crystal
structure.
O hydrogen bonds may be effective in its stabilization.
O hydrogen bonds, forming chains along the a axis in the crystal structure.
O hydrogen-bonding interactions. O interactions into a
three-dimensional network.
The carboxylic acid transfers its acid H atoms to two molecules of
atenolol; the cation, anion and water molecule are linked through
hydrogen bonds into a three-dimensional network motif.
O hydrogen bonds link adjacent molecules, forming an infinite network.
O hydrogen bonds may be effective in its stabilization.
The cyclohexane ring adopts a chair conformation and the olefinic
double bond has Z geometry.
O hydrogen bond links molecules into one-dimensional chains along the a axis.
Two equivalent six-membered triazine rings bind the N atoms from
separate rings of the glycouril unit to form the flexible sidewalls of
a molecular clip.
The succinate anion is located on an inversion center.
Br interactions, leading to chains of molecules.
O hydrogen-bonding interactions.
O hydrogen bonds link molecules, forming an infinite network. The
cyclohexadienone ring is planar, the cyclohexane and cyclohexene
rings adopt chair and sofa conformations, respectively, while the
cyclopentene ring adopts an envelope conformation.
O hydrogen bond involving a sulfonate O atom of the cation.
The succinate anion is located on an inversion center. The
naphthofuran ring system is approximately planar.
The hydrogen bonds in the crystal structure seem to be too weak to
generate any deformations observed in the molecule.
There is evidence of significant electron delocalization in the
triazolyl system.
The anions are located on crystallograpic twofold axes. S
interactions, forming one-dimensional zigzag chains along the b axis.
The cation is almost planar and exists in an E configuration. O
contacts exist between dimers. Intermolecular hydrogen bonds between
amide N and amide O atoms of neighbouring molecules allow the
construction of a two-dimensional network.
The carboxylic acid transfers its acid H atoms to two molecules of
atenolol; the cation, anion and water molecule are linked through
hydrogen bonds into a three-dimensional network motif.
The conformations of these non-planar molecules are simlilar.
S interactions, forming one-dimensional zigzag chains along the b
axis. One of the three fused cyclohexane rings adopts a half-chair
conformation and the other two cyclohexane rings are in standard chair
conformations.
