2-Fluoro-N'-[(2-meth-oxy-naphthalen-1-yl)methyl-idene]benzohydrazide.

The asymmetric unit of the title compound, C(19)H(15)FN(2)O(2), contains two mol-ecules, A and B, in which the dihedral angles between the ring systems are 46.4 (2) and 17.24 (14)°, respectively.

3-Bromo-N'-[(2-meth-oxy-naphthalen-1-yl)methyl-idene]benzohydrazide.

The mol-ecule of the title compound, C(19)H(15)BrN(2)O(2), displays a pseudo-trans conformation about the N-N bond [C-N-N=C torsion angle = 164.7 (2)°]. The dihedral angle between the planes of the benzene ring and the naphthyl system is 70.

Di-μ(1,1)-azido-bis-[(2-{1-[2-(isopropyl-amino)ethyl-imino]eth-yl}phenolato)copper(II)].

In the centrosymmetric binuclear title complex, [Cu(2)(C(13)H(19)N(2)O)(2)(N(3))(2)], the Cu(II) atom adopts an elongated CuON(4) square-based pyramidal coordination geometry, arising from the N,N',O-tridentate ligand and two bridging end-on azide anions. The O atom is in the basal plane, one of the azide N atoms is in the apical site and the Cu⋯Cu separation is 3.2365 (3) Å.

3-Bromo-N'-(2-hydroxy-benzyl-idene)benzohydrazide.

The title mol-ecule, C(14)H(11)BrN(2)O(2), displays a trans configuration about the C=N and C-N bonds. The dihedral angle between the two benzene rings is 18.5 (3)°.
