چکیده
The title complex, [Li4(C17H14N4)2(C4H8O)4], bears a novel tetra-dentate di-amido ligand. In the tetra-nuclear centrosymmetric complex mol-ecule, the metal atoms exhibit two kinds of coordination modes. The middle two Li(+) cations are coord-inated by four N (ligand) and one O (tetra-hydro-furan, THF) atoms, resulting in a distorted square-pyramidal geometry. The outer two Li(+) cations are in distorted tetra-hedral environments consisting of three N (ligand) and one O (THF) atoms. The Li-N bond lengths vary from 2.020 (7) to 2.441 (6)Å.

The title compound, C(22)H(18)N(2)O, was synthesized from naphthalen-2-ol, benzaldehyde and pyridin-2-amine. In the crystal, mol-ecules are linked into centrosymmetric R(2) (2)(16) dimers by pairs of O-H⋯N hydrogen bonds. The mol-ecular conformation is stabilized by an N-H⋯O hydrogen bond. The dihedral angle between the naphthylene ring system and the phenyl ring is 72.86 (12)°.

In the title compound, [CuCl(C17H19Cl4N3)]ClO4, the Cu(II) ion adopts a distorted square-planar geometry defined by one chloride ligand and the three nitro-gen atoms from the bis-[(pyridin-2-yl)meth-yl](3,5,5,5-tetra-chloro-pent-yl)amine ligand. The perchlorate counter-ion is disordered over three sets of sites with refined occupancies 0.0634 (17), 0.221 (16) and 0.145 (7). In addition, the het...

The title compound, 2C(21)H(34)N(4)O(3)S(2+)·4I(-)·5H(2)O, was prepared exclusively as the E isomer by methyl-ation of the corresponding N-phenyl-pyridin-4-amine. There are two symmetry-independent mol-ecules in the asymmetric unit with no significant differences in bond lengths and angles. The aromatic rings are not coplanar with the pyridin-4-imine groups, as indicated by the C-N-C-C torsion ...
