The molecule contains five six-membered rings, two five-membered rings and a three-membered ring. O hydrogen bonds that link adjacent molecules into one-dimensional extended chains.
O hydrogen bonding and S. The plane of the ester group is almost perpendicular to the planes of the two aromatic rings. O intramolecular hydrogen bonds lead to the formation of a sequence of five-, six- and five-membered rings, respectively, which are edge-fused.
All bond lengths and angles show normal values. O hydrogen bonds that link adjacent molecules into one-dimensional extended chains. In the crystal structure, the molecules are aligned in an antiparallel fashion to form alternate layers. The conformations of the rings are nearly envelope, nearly planar and envelope. N hydrogen bonds, leading to a chain structure. All bond lengths and angles show normal values.
N hydrogen bonds, forming a wide ribbon-like structure extending in the ac plane.
The plane of the ester group is almost perpendicular to the planes of the two aromatic rings.
O hydrogen bonds, linking the molecules into chains.
, tert-butyl, aryl, bromo and methoxy groups, the former two occupy equatorial positions and the latter two are placed axially on the cyclohexanone ring.
The atomic arrangement is characterized by hydrogen selenate tetrahedra and trigonal guanidinium groups, which are connected to each other by a network of mostly weak hydrogen bonds.
S interactions promote two-dimensional packing parallel to the ac plane, and form a three-dimensional network. S interactions promote two-dimensional packing parallel to the ac plane, and form a three-dimensional network.
O hydrogen bonds, linking the molecules into chains. O hydrogen bonds, linking the molecules into chains.
N hydrogen bonds together with weak N. O interactions are found in the crystal structure. O hydrogen bonds that link adjacent molecules into one-dimensional extended chains.
O hydrogen bonds, linking the molecules into chains.
The atomic arrangement is characterized by hydrogen selenate tetrahedra and trigonal guanidinium groups, which are connected to each other by a network of mostly weak hydrogen bonds. O interactions, forming ribbons along the a axis.
N hydrogen-bonding interactions which give rise to dimers in the solid state.
All atoms are located on general positions. O interactions form a hydrogen-bonded network.
The molecule contains five six-membered rings, two five-membered rings and a three-membered ring.
O hydrogen bonds link adjacent molecules, forming a two-dimensional network. The are two molecules in the asymmetric unit.
Each molecule is nearly planar and they are roughly parallel to each other.
The other two N atoms are each linked to an O atom by methylene groups, forming a six-membered ring. O hydrogen bonds, forming a three-dimensional network in the crystal structure. O hydrogen bonds, linking the molecules into chains. The water molecules participate in extensive hydrogen bonding and link molecules into a two-dimensional network. N hydrogen bonds together with weak N.
