S intermolecular interactions. The chains are further stabilized in ribbons by Cl. Geometric parameters are in the normal ranges.
The data reveal that some strain is probably present in the bicyclic structure. O hydrogen bonds link the molecules into chains running along the a axis.
The N and C atoms of the cation, together with their attached H atoms, lie on the same mirror plane. The two imino groups are hydrogen bonded with the dimethyl sulfoxide solvent molecule.
O hydrogen bonds help to consolidate the crystal structure.
O intermolecular hydrogen bonds. The crystal structure is stabilized by short intermolecular Br.
O intermolecular hydrogen bonds. S intermolecular hydrogen bonds, forming a two-dimensional network.
O intermolecular hydrogen bonds link the molecules into ribbons along the c axis. The two imino groups are hydrogen bonded with the dimethyl sulfoxide solvent molecule.
The bond lengths within the system indicate some degree of delocalization.
O hydrogen bonds help to consolidate the crystal structure.
The carboxylate group is oriented almost coplanar with the indolizine unit. S hydrogen bond stabilizes the molecular structure.
Intramolecular hydrogen bonding is observed between the carbonyl group and the hydroxy group.
O short-contact interactions. The N and C atoms of the cation, together with their attached H atoms, lie on the same mirror plane. O hydrogen bonds, forming infinite chains along the c axis.
O hydrogen-bond acceptor to the amide and amine groups of two adjacent molecules, resulting in a layered structure.
The crystal structure contains three very weak intermolecular hydrogen bonds, viz.
