چکیده
In the title mol-ecule, C(25)H(26)N(4)O, the piperidine ring adopts a chair conformation, with the plane through the four coplanar atoms making dihedral angles of 84.76 (6), 82.28 (5) and 81.91 (6)° with the pyridine-ring and the phenyl rings at the 2 and 6 positions, respectively. The pyridine ring makes dihedral angles of 64.13 (8) and 10.75 (8)° with the phenyl rings at the 2 and 6 positions, respectively. The dihedral angle between the two phenyl rings is 53.57 (8)°. The phenyl rings and one of the methyl groups at position 3 have an equatorial orientation. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds.

The backbone of the title mol-ecule, C(26)H(25)BrN(4)O, is approximately planar: the dihedral angle between the planes of the indoline ring system and the furan ring is 7.68 (14)°. In the crystal, layers lying parallel to (10) occur, with the mol-ecules inter-acting via weak C-H⋯N(cyano) and C-H⋯Br bonds and short N(cyano)⋯Br contacts [3.345 (4) Å].

The title compound, C(29)H(28)N(4)O(2), excluding the hydroxyethyl and methyl groups, is slightly twisted from planarity so that the terminating indol-2-yl-idene and furan-2-yl-idene moiety planes subtend a dihedral angle of 6.27 (8)°. A small inwards fold in the polymethine atom chain is consistent with centrosymmetric dimer formation via O-H⋯N(cyano) hydrogen bonds. In the crystal, the mol-ec...
