Dimethyl 2,5-bis(5-hexylthiophen-2-yl)benzene-1,4-dioate
In the title compound, C(30)H(38)O(4)S(2), the centroid of the benzene ring lies on a center of inversion. The thio-phene ring is aligned at 49.8 (1)° with respect to the benzene ring. The alkyl chain adopts an extended zigzag conformation.

The title compound, C(29)H(33)NO(8), is a product of the Michael addition of the cyclic secondary amine subunit of the aza-14-crown-4 ether to dimethyl acetyl-enedicarboxyl-ate. The piperidinone ring exhibits a distorted chair conformation, and the dimethyl ethylenedicarboxylate fragment has a cis configuration with a dihedral angle of 78.96 (5)° between the two carboxyl-ate groups. The crystal...

In the title compound, C(15)H(15)NO(4), the quinoline ring system and one of the malonate side chains are essentially coplanar (r.m.s. deviation = 0.0297 Å). The two malonate C-C(=O)-O-CH(3) side chains are oriented at right angles [89.68 (8)°] with respect to each other. The crystal packing is stabilized by weak non-classical inter-molecular C-H⋯O hydrogen bonds, which link the mol-ecules into...
متن کاملDimethyl 2-(methylaminomethylene)malonate
In the title compound, C(7)H(11)NO(4), which is an example of a push-pull alkene, a network of N-H⋯O and C-H⋯O inter-actions helps to establish the crystal structure. The investigated crystal turned out to be a non-merohedral twin with a ratio of twin components of 0.442 (3):0.558 (3). Two pairs of independent mol-ecules (Z' = 4) are linked by inter-molecular N-H⋯O hydrogen bonds, forming indep...
