O hydrogen bonds, forming a network. O hydrogen bonds link the molecules into chains running along the a axis.
N interactions connect these chains into a two-dimensional layer.
O intermolecular hydrogen bonds.
The bond lengths within the system indicate some degree of delocalization.
The crystal packing is further stabilized by van der Waals forces. The crystal structure contains three very weak intermolecular hydrogen bonds, viz.
The latter links molecules into infinite chains. The crystal structure is stabilized by short intermolecular Br. The six-membered rings have chair conformations, while the conformation of the five-membered ring is an envelope. O hydrogen bonds link the molecules into chains extended along the b axis.
O intermolecular hydrogen bonds. As a result of the synthetic precursor being enantiomerically pure, only the R,R enantiomer occurs in the structure. O hydrogen bonds stabilize the structure. O interactions are observed. O hydrogen bonds, forming a chain.
O short-contact interactions.
These dimers are located around centres of inversion.
The N and C atoms of the cation, together with their attached H atoms, lie on the same mirror plane. O hydrogen bonds into a three-dimensional network. O hydrogen bonds, leading to zigzag chains along the b axis.
O hydrogen bonds link the molecules into chains running along the a axis. Geometric parameters are in the normal ranges.
The crystal structure contains three very weak intermolecular hydrogen bonds, viz.
O hydrogen bonds, resulting in inversion-symmetry generated dimers. The trimethylsilyl group is substituted in the axial position of the half-chair.
O hydrogen bonds, forming a chain. S intermolecular hydrogen bonds, forming a two-dimensional network.
O hydrogen bonds, forming a network. O hydrogen bonds stabilize the structure.
There are two crystallographically independent molecules in the asymmetric unit. O hydrogen bonds that form centrosymmetric dimers.
There are two crystallographically independent molecules in the asymmetric unit. In the molecule, two thiazoline rings are located on one side of the central benzene plane, while the third thiazoline ring is located on the other side of the central benzene plane.
