The title compound, [Ti(C19H23NO2)2]·1.5C7H8, crystallizes with one titanium complex mol-ecule per asymmetric unit together with one and a half toluene mol-ecules. The Ti(IV) atom is coordinated by two fully deprotonated O,N,O'-tridentate phen-oxy-amine ligands in a distorted octa-hedral environment. Within this arrangement the O atoms occupy the equatorial sites and the N atoms the axial sites...

The Mn(III) atom in the title complex, [Mn(C(18)H(18)N(2)O(4))(CHO(2))(H(2)O)]·2H(2)O, is O,N,N',O'-chelated by the deproton-ated Schiff base; the four chelating atoms form an approximate square, with the O atoms of the water mol-ecule and the formate ion in axial positions above and below the square plane. Two metal-bearing mol-ecules are linked by an O-H(water)⋯O hydrogen bond about a center ...

The asymmetric unit of the title compound, C(18)H(29)NO(3), contains two independent mol-ecules.

In the crystal structure, weak C-H⋯O hydrogen bonds link mol-ecules into double-layer ribbons extending in [110].

In the title mol-ecule, C(18)H(14)N(2)O(3), O-H⋯N and N-H⋯O hydrogen bonds influence the mol-ecular conformation; the benzene and naphthalene planes are inclined at a dihedral angle of 11.54 (5)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains running in the [01] direction.

The title compound, C(15)H(16)ClN(5)O, contains two mol-ecules, A and B, in the asymmetric unit, in which the dihedral angles between the terminal aromatic rings are 42.41 (17) and 45.77 (18)°. The central six-membered ring in both mol-ecules has a chair conformation with equatorial substituents. In the crystal, mol-ecules are linked into [100] C(4) chains of alternating A and B mol-ecules by N...

There are two independent mol-ecules in the asymmetric unit of the title compound, C(26)H(26)N(4)OS. In each mol-ecule, the thienopyrimidine fused-ring system is essentially planar with a maximum deviation of 0.0409 (18) for the N atom. In one mol-ecule, this ring system forms diherdral angles of 84.8 (1) and 67.6 (1)° with the adjacent phenyl and benzyl rings, respectively, while the correspon...

There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(18)N(2), each of which features a syn disposition of the N atoms. In each mol-ecule, the pyrrole and benzene rings are essentially perpendicular, with dihedral angles of 78.90 (9) and 79.96 (9)°. In the crystal, the independent mol-ecules are connected by a pair of pyrrole-imino N-H⋯N hydrogen bonds, formi...

The asymmetric unit of the title compound, C(18)H(20)N(2)O(4), contains one-half mol-ecule with an inversion center located at the centroid of the mol-ecule.
