چکیده
In the title compound, C(9)H(10)N(2)O(4)S, which is an important inter-mediate for the preparation of anti-tumor platinum drugs, the dioxolane ring adopts an envelope conformation with the C atom bonded to the thienyl ring at the flap position. Intra-molecular N-H⋯O and C-H⋯O hydrogen bonds result in the formation of two five-membered rings having envelope conformations. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

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...
