title: 3,3'-Dihydroxy-5,5,5',5'-tetramethyl-2,2'-thiodicyclohex-2-en-1-one.
abstract: Molecules of the title compound, C(16)H(22)O(4)S, have twofold crystallographic symmetry and are stabilized by strong intramolecular O-H...O hydrogen bonds and very weak intermolecular C-H...O hydrogen bonds, forming layers normal to the c axis. The molecular structure is compared with those of the Se- and CH(2)-bridged analogues.
