The origin of synthons and supramolecular motifs: beyond atoms and functional groups

The origin of synthons and supramolecular motifs: beyond atoms and functional groups

A four-membered R22(4) supramolecular motif formed by S...S and S...I chalcogen-bonding interactions in the crystal structure of 4-iodo-1,3-dithiol-2-one (C3HIOS2, IDT) is analysed and compared with a similar R22(4) motif (stabilized by Se...Se and Se...O chalcogen bonds) observed in the previously...
