چکیده
The title compound, C(28)H(28)N(2)O, was prepared by condensation of 1,2-bimethyl-indole and 4-methoxy-benzaldehyde. In the mol-ecular structure, the plane of the non-fused benzene ring is twisted with respect to the planes of the two indole ring systems, exhibiting dihedral angles of 72.04 (7) and 72.24 (7)°, while the planes of the two indole ring systems are oriented at a dihedral angle of 87.05 (5)°. Neither hydrogen bonding nor π-π stacking is observed in the crystal structure.

The title compound, [Ti(C24H33O2)Cl3(C4H8O)], is a rare example of a trigonal-bipyramidal titanium coordination complex with three chloride and two oxygen donor ligands. The asymmetric unit contains two independent mol-ecules having essentially the same conformation. The mol-ecules feature the titanium(IV) metal cation complexed with three chloride ligands, a tetra-hydro-furan mol-ecule, and on...

The two title compounds, C28H26N2O2, (I), and C27H22BrClN2O2, (II), differ in their substituents, viz.4-methyl-phenyl and benzoyl rings in (I) replaced by 2-chloro-phenyl and 4- bromo-benzoyl, respectively, in (II). A significant difference between the two mol-ecules is found in the deviation of the benzoyl O atom from the least-squares plane of the ring to which it is attached [0.593 (4) and 0...
