The molecule is approximately planar for all non-H atoms. The bond lengths within the system indicate some degree of delocalization. The complete molecule is located on a crystallographic mirror plane. O hydrogen bonds link the molecules into zigzag chains along the b axis. O contacts in the structure. Cl hydrogen bonds link cations and anions to form one-dimensional ladders propagating in the a-axis direction. Each conformer resides on a centre of inversion. The cation and all atoms of the anion lie on a mirror plane. As a result of the synthetic precursor being enantiomerically pure, only the R,R enantiomer occurs in the structure. O hydrogen bonds, forming a three-dimensional hydrogen-bond network. The ethoxybenzene and chlorophenyl rings are located on the same side of the heterocyclic system, resembling the two front claws of a crab. Apart from the hydroxy group, the molecule is essentially planar. O hydrogen bonds, forming centrosymmetric dimers. N hydrogen-bond interactions are present, resulting in a one-dimensional supramolecular chain structure. The bond lengths are normal. O contacts in the structure. O hydrogen bonds, forming a network. O hydrogen bonds link the molecules into dimers, which may be effective in the stabilization of the crystal structure. The bond lengths are normal. O hydrogen bonds, forming centrosymmetric dimers. O hydrogen bonds into a three-dimensional network. N hydrogen bond with an O. O hydrogen bonds, forming a network. N hydrogen bonds link the molecules into centrosymmetric dimers. O hydrogen bonds, generating two edge-fused motifs, viz. N hydrogen bond, which stabilizes the configuration. An intramolecular hydrogen bond occurs between the oxazole and hydroxy groups. |
