Crystal structure of 1,3,4-triphenyl-pyrrole-2,5-dione.
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 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...

component for functional dyes because it contains two electronwithdrawing and one electron-donating groups. Studies to understand how substituents to the 1H-pyrrole-2,5-dione skeleton influence its structure and properties are of particular interest from the viewpoint of the development of novel functional dyes. We determined the structure of 1,3,4triphenyl-pyrrole-2,5-dione (Fig. 1(I))1 and de...
