3,4-Bis(4-meth-oxy-phen-yl)-2,5-dihydro-1H-pyrrole-2,5-dione.

ABSTRACT: In the title compound, C(18)H(15)NO(4), the benzene rings form quite different dihedral angles [16.07?(1) and 59.50?(1)°] with the central pyrrole ring, indicating a twisted mol-ecule. Conjugation is indicated between the five- and six-membered rings by the lengths of the C-C bonds which link them [1.462?(3) and 1.477?(3)?Å]. The most prominent feature of the crystal packing is the formation of inversion dimers via eight-membered {?HNCO}(2) synthons.

3,4-Dibromo-2,5-bis-[(dieth-oxy-phosphor-yl)meth-yl]-1-phenyl-sulfonyl-1H-pyrrole.

Project description:In the title compound, C(20)H(29)Br(2)NO(8)P(2)S, the pyrrole ring is essentially planar, with a maximum deviation of 0.013 (3) Å for a C atom. The pyrrole ring is almost orthogonal to the sulfonyl-bound phenyl ring, with a dihedral angle 88.5 (2)°. Both P atoms exhibit distorted tetra-hedral configurations with O-P-O angles widened and O-P-C angles narrowed from the ideal tetra-hedral value. In the crystal, mol-ecules are linked into centrosymmetric dimers via C-H⋯O inter-actions, resulting in R(2) (2)(10) graph-set motifs which are further consolidated by R(2) (2)(13) graph-set ring motifs via C-H⋯O inter-actions, further resulting in chains of mol-ecules running parallel to the c axis; a phosphono O atom is involved in bifurcated hydrogen bonding. All the eth-oxy groups are disordered over two positions each with unequal site-occupancy factors.

3,4-Bis[1-(prop-2-yn-yl)-1H-indol-3-yl]-1H-pyrrole-2,5-dione.

Project description:In the title mol-ecule, C26H17N3O2, both indole ring systems are essentially planar, with maximum deviations of 0.019 (2) and 0.033 (1) Å for the N atoms, and form dihedral angles of 34.40 (9) and 45.06 (8)° with the essentially planar pyrrole ring [maximum deviation = 0.020 (2) Å]. The dihedral angle between the two indole ring systems is 58.78 (6)°. In the crystal, mol-ecules are connected by pairs of N-H⋯O hydrogen bonds, forming inversion dimers and generating R 2 (2)(8) rings.
