organic compounds
In the title compound, C11H13NOS, the thiophene ring is planar while the central six-membered ring has a half-chair conformation and the second ring of the quinolizine moiety is in a chair conformation. The angles at the N atom sum to 331.22°, indicating pyramidalization of this atom.
organic compounds
The crystal structure of the title compound, C18H19N3O3S, is formed by single molecules linked by N—HO hydrogen bonds into infinite linear chains along the ac diagonal. The thiophene ring is nearly planar and is approximately perpendicular to the mean plane of the 1,4-dihydropyridine ring. The ester group has a trans geometry with respect to the adjacent ring double bond. The dihydropyridine and pyrrole rings are coplanar.
metal-organic compounds
In the title octahedral complex, [Cu{N(CN)2}2(ampym)2]n (ampym is 4-aminopyrimidine, C4H5N3), the Cu atom is located on an inversion centre and is coordinated in the equatorial plane by two dicyanamide nitrile N atoms and two N atoms from ampym ligands [Cu—N = 1.972 (2) and 2.001 (2) Å, respectively], and in the axial positions by another two dicyanamide nitrile N atoms, at 2.633 (2) Å. Neighbouring Cu atoms are connected via double dicyanamide bridges to form a one-dimensional infinite chain.
organic compounds
The crystal structure of the title compound, C13H13NO3, is stabilized by dipole-dipole and van der Waals forces. The pyrrolidine ring is almost planar, while the central six-membered ring of the indolizine moiety adopts a sofa conformation.
