title: [(4S,5S)-2,2-Dimethyl-1,3-dioxolane-4,5-di-yl]bis-[N-(thio-phen-2-yl-methyl-idene)methanamine].
abstract: In the title compound, C(17)H(20)N(2)O(2)S(2), the five-membered heterocycle exhibits an envelope conformation and the mol-ecular chirality and configuration are well preserved from l-tartaric acid. The dihedral angle between the two thio-phene rings is 17.0 (2)°. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯S hydrogen inter-actions, which are effective in the stabilization of the crystal structure.
