چکیده
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.

In the chiral title compound, C(15)H(22)N(4)O(2)S(2), there are two mol-ecules in the asymmetric unit with distinctly different conformations, as quanti-fied by torsion angles. The dihedral angles between the thio-imidazole rings are 81.59 (5) and 67.04 (4)°. One mol-ecule exhibits local twofold rotation symmetry, while the other displays no local symmetry. Inter-molecular C-H⋯O and C-H⋯S inter...

In the title four-coordinate complex, [Ti(C(2)H(6)N)(2)(C(31)H(28)O(4))], two symmetry-independent mol-ecules are present in the asymmetric unit. The Ti(IV) atom displays a distorted tetra-hedral geometry, with Ti-O bond lengths ranging from 1.805 (3) to 1.830 (3) Å and O-Ti-O ligand bite angles of 100.16 (12) and 101.36 (12)°. The short Ti-N bond distances, ranging from 1.877 (4) to 1.905 (4) ...

The title compound, C7H8N2O2, formed by dehydration of the corresponding dicarboxamide, crystallizes as rectangular prisms. The mol-ecules have a C 2 axis of symmetry through the C atom bearing the methyl groups and the mid-point of the ring C-C bond, and the 1,3-dioxolane ring adopts the extreme twist conformation of the two possible with this symmetry. This brings the two nitrile groups neare...
