withdrawing groups and an electron-donating group. The electron-withdrawing groups are further conjugated with a double bond in the ring. The light-absorption characteristics of the molecule are expected to be modified by changing the substituents attached to the molecule. This indicates that the molecule can be one of the basic components in designing functional dyes. It is therefore of partic...
متن کاملCrystal structure of 1-(piperidin-1-yl)butane-1,3-dione
In the title compound, C9H15NO2, the piperidine ring exhibits a chair conformation. The butane-dione subunit exhibits a conformation with the ketone C atom in an eclipsed position with respect to the amide carbonyl group. In the crystal, a two-dimensional layered arrangement is formed by hydrogen bonds of the C-H⋯O type between the methyl group and the exocyclic methyl-ene unit as donor sites a...
متن کامل1,10-Phenanthroline-5,6-dione ethanol monosolvate
In the title compound, C12H6N2O2·C2H5OH, the mol-ecule of the 1,10-phenanthroline-5,6-dione is approximately planar, with a maximum deviation of 0.051 (1) Å. In the crystal, mol-ecules are linked by O-H⋯N and weak C-H⋯O hydrogen bonds, forming supra-molecular chains propagating along [110]. π-π stacking inter-actions are observed between the pyridine rings of neighbouring chains, the centroid-c...
متن کاملCrystal structure of 1-ethylspiro[imidazolidine-4,1′-indane]-2,5-dione
In the title compound, C13H14N2O2, the C5 ring has an envelope conformation with the C atom adjacent to the quaternary C being the flap. The five atoms comprising the imidazolidine-2,4-dione ring are almost planar (r.m.s. deviation = 0.004 Å). The dihedral angle between the five-membered rings is 89.66 (10)°. In the crystal, inversion-related mol-ecules are connected via {⋯HNCO}2 synthons. Thes...
متن کاملCrystal structure of 6,6,12,12-tetrachlorotricyclo[8.2.0.04,7]dodecane-5,11-dione
The asymmetric unit of the title compound, C12H12Cl4O2, contains two crystallographically independent mol-ecules with almost identical conformations (r.m.s. overlay fit for the non-hydrogen atoms = 0.059 Å). In each mol-ecule, the central eight-membered ring has a distorted boat configuration, and two non-planar four-membered rings are fused on either side of the eight-membered ring. A weak C-H...
