In the title Schiff base, C(15)H(14)FN, the N=C bond length of 1.263 (2) Å is shorter than the N-C bond [1.426 (2) Å], indicating a typical imine double bond. Moreover, the C-N-C angle is 118.5 (2)°. The benzene rings form a dihedral angle of 51.22 (5)°.
In the title Schiff base complex, [Zn(C(14)H(9)Br(2)FNO)(2)], the Zn(II) atom is located on a twofold rotation axis and is coordinated by two O and two N atoms from two symmetry-related bidentate Schiff base ligands in a compressed tetrahedral geometry. The bond lengths and bond angles are within normal ranges. The dihedral angle between the least-squares… (More)
In the title Schiff base, C(15)H(14)FNO(2), the dihedral angle between the benzene rings is 53.32 (8)°. In the crystal, mol-ecules related by a twofold rotation axis are linked by pairs of C-H⋯O hydrogen bonds into dimers with R(2) (2)(18) ring motifs. An intra-molecular O-H⋯N hydrogen bond is also observed.
The title compound, C(20)H(16)N(6), is centrosymmetric with the mid-point of the N-N bond located on an inversion center. The imidazole ring is oriented at a dihedral angle of 28.03 (6)° with respect to the attached benzene ring. In the crystal, molecules are linked via C-H⋯N interactions.
In the title Schiff base compound, C(15)H(14)FNO, the benzene rings make a dihedral angle of 72.75 (13)°. The mol-ecular structure is stabilized by an intra-molecular O-H⋯N hydrogen bond. In the crystal, weak π-π stacking occurs between the phenol rings of inversion-related mol-ecules, the centroid-centroid distance being 3.7731 (14) Å.
The complete mol-ecule of the title complex, [Co(C(14)H(9)Br(2)FNO)(2)], is generated by crystallographic twofold symmetry, with the Co(II) atom lying on the rotation axis. The coordination of the metal atom by the two N,O-bidentate ligands results in a squashed CoN(2)O(2) tetra-hedron. The six-membered chelate ring is an envelope, with the metal atom as… (More)
