(4E)-4-[(2-Hy­droxy­anilino)methyl­idene]-1-phenyl­pyrazolidine-3,5-dione dimethyl sulfoxide hemisolvate

The asymmetric unit of the title compound, C(16)H(13)N(3)O(3)·0.5C(2)H(6)OS, is composed of two independent pyrazolidine-3,5-dione mol­ecules and one dimethyl sulfoxide solvent mol­ecule. In each pyrazolidine-3,5-dione mol­ecule, an intra­molecular N—H⋯O hydrogen bond forms an S(5)S(6) motif. In the...

Descripción
Sumario:The asymmetric unit of the title compound, C(16)H(13)N(3)O(3)·0.5C(2)H(6)OS, is composed of two independent pyrazolidine-3,5-dione mol­ecules and one dimethyl sulfoxide solvent mol­ecule. In each pyrazolidine-3,5-dione mol­ecule, an intra­molecular N—H⋯O hydrogen bond forms an S(5)S(6) motif. In the crystal, pairs of each independent pyrazolidine-3,5-dione mol­ecule are linked by N—H⋯O hydrogen bonds, forming dimers with R (2) (2)(8) motifs. These dimers are connected with the other mol­ecules through the solvent mol­ecules via O—H⋯O hydrogen bonds, forming ribbons along the b-axis direction. C—H⋯π inter­actions connect the ribbons. C—H⋯O interactions also occur.
