Crystal structure of 2-[bis(benzylsulfanyl)methyl]-6-methoxyphenol.

The title compound, C22H22O2S2, 1, represents an example of an ortho-vanillin-based functionalized di-thio-ether, which could be useful as a potential chelating ligand or bridging ligand for coordination chemistry. This di-thio-acetal 1 crystallizes in the ortho-rhom-bic space group Pbca. The phenyl rings of the benzyl groups and that of the vanillin unit form dihedral angles of 35.38 (6) and 79.77 (6)°, respectively. The crystal structure, recorded at 100 K, displays both weak intra-molecular O-H⋯O and inter-molecular O-H⋯S hydrogen bonding.
