چکیده
The mol-ecule of the title compound, C19H15N3O2, is completed by the application of crystallographic twofold symmetry, with the pyridine N atom lying on the rotation axis. The mol-ecular structure is approximately planar, the dihedral angle between the mean planes of the pyridine and benzene rings being 7.53 (11)°. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional array perpendicular to the c axis.

In the crystal structure of the title compound, [Ni(C(21)H(19)N(5)O(4)S(2))(C(5)H(5)N)(2)], the metal center is seven-coordinate, with an approximate penta-gonal-bipyramidal configuration. The Ni atom is chelated by a dianionic penta-dentate Schiff base via the pyridine N atom, the two azomethine N atoms and the two sulfonyl O atoms. The latter coordinate to Ni at different distances, viz. 2.33...

The title compound, C21H9F10N3, represents a potential redox non-innocent pyridine di-imine ligand system. It consists of a central pyridine ring with two penta-fluoro-phenyl substituted imine groups in positions 2 and 6. The whole mol-ecule is generated by mirror symmetry, the mirror bis-ecting the N and para-C atom of the pyridine ring. The perfluoro-phenyl ring is inclined to the pyridine ri...

The Au atom in the C2-symmetric pincer-type title complex, [AuCl(C(19)H(23)N(5))], is in the +3 oxidation state. The ligand is composed of one pyridine unit and two n-butyl-substituted pyrazoles (pyrz). Both pyrazoles are deprotonated, thus forming a neutral compound. To the best of our knowledge, this is the first Au(III)-bis-pyrazolate complex. According to the special geometry in the N,N',N'...
