organic compounds
The title compound, C15H11Cl2NO, was synthesized from N-benzylisatin. The compound crystallizes as stacks of molecules running down the c axis. Molecules within each of these stacks interact with each other through π–π and C—Hπ interactions, and interact with neighbouring stacks through C—HO interactions.
organic compounds
The title compound, C20H19NO5S2, crystallizes as an almost 2:1 mixture of two molecular orientations (described as Orient-A and Orient-B). The consequences of these two orientations is the formation of three types of N—HO hydrogen-bonded dimers in which the (Orient-A + Orient-A) dimers are likely to be the most stable, while the mixed (Orient-A + Orient-B) dimers are more frequent. Extra interactions in the form of C—HO and C—Hπ interactions act to further stabilize these dimers and probably allow the less energetically favourable (Orient-A + Orient-B) and (Orient-B + Orient-B) hydrogen-bonded dimers to exist by preventing their conversion to (Orient-A + Orient-A)-only hydrogen-bonded dimers during the crystal-growth process.
