Figure 4
Packing and non-classical hydrogen-bonding motifs for the crystal structures of bis[4-methyl-1,3-ene-dithiol-2-one] disulfide and bis[4-methyl-1,3-ene-dithiol-2-one] diselenide. Left: C4—H4B⋯O1ⁱ interactions zigzagging along the b axis shown for the diselenide; center: hydrogen-bonding interactions of the diselenide bridge C5—H5C⋯Se1ⁱⁱ protruding along the c axis; right: additional symmetric hydrogen-bonding interactions between coplanar 1,3-ene-dithiol-2-one moieties connecting adjacent chains shown for the disulfide (C4—H4C⋯S2^iv and C5—H5C⋯S5ⁱⁱⁱ). For symmetry codes, see Tables 1
