In this paper, we describe how the crystal structures of 5-benzylidenerhodanines are influenced by substituents onthe phenyl ring and those of 5-cycloalkylidenerhodanines by the size of the cycloalkane ring. Although the R^2/2(8) (CONH)₂ ringof rhodanine is generally retained in these structures, the dimers so created are associated in a wide variety of ways, often throughweak interactions such as C-H···S/O, C-H···, or Br···S/O bonds. In some cases, solvent molecules present in the lattice alsoplay a significant role in the self-organization of the crystals.
