Abstract

The structures of the title compounds, Csb 17Hsb 20BrClNsb 2Osb 3, (I), and Csb 17Hsb 19ClN 2Osb 3, (II), are stabilized by intramolecular C-H⋅sO and C-H⋅sπ interactions. The stability of the molecular packing in (I) and (II) arises from a diverse set of weak intermolecular C-H⋅sO, C-H⋅sπ and C-halogen⋅sπ interactions. In the crystal structure of (I), mol-ecules aggregate in dimeric subunits it via C-Br⋅sπ interactions. The dimers are interlinked by C-H⋅sO hydrogen bonds. The halogens cluster together and form a channel along the it b axis. In (II), the packing is mainly governed by intermolecular C-H⋅sO and C-H⋅sπ interactions.
