In the title compound, C 10 H 22 N 4 S 2 , molecules lie across crystallographic inversion centres. Weak N-HÁ Á ÁN and N-HÁ Á ÁS hydrogen-bonding interactions are observed in the molecular structure.
The title compound, C 17 H 19 NO 4 , was synthesized by the Stobbe condensation reaction of p-dimethylaminobenzaldehyde and diethyl succinate, followed by cyclization of the Stobbe product. The crystal structure is stabilized by intermolecular C-HÁ Á Á interactions.
The title compound, C 2 H 8 N + ÁC 10 H 5 O 8 À , contains discrete ethylammonium cations and singly deprotonated pyromellitate anions. The geometry of the ethylammonium cation is not significantly different from that in other structures containing this residue. The pyromellitate anion is non-planar
The crystal structure of ethyl 2,3,5,6-tetramethylbenzoate, C 13 H 18 O 2 , has been determined and torsion angles are compared to those previously reported in a dipole moment study of substituted benzoates.
In the title compound, C~25~H~23~N~3~O~3~, molecules are linked into chains along the __c__ axis by intermolecular C—H...O hydrogen bonds. The packing is further stabilized by C—H...π and π–π interactions.
