cis,cis-1,3,5-tris[(E)-(X)-benzylideneamino]cyclohexane
[X = H (1); 3-hydroxy
(2); 3,5-dimethoxy (3); 4-acetamido
(4)] are synthesized by the condensation of
cis,cis-1,3,5-triaminocyclohexane
with a substituted aromatic aldehyde. Complexation of these
ligands with metal salts (1 with Ni, Cu, and Zn
salts; 2 and 3 with Cu salts; 4 with a
Zn salt) causes a selective hydrolysis reaction producing new
monoimine
complexes. The resulting complexes are characterized by a
combination of infrared spectroscopy, elemental
analysis, mass spectrometry and, in the cases of the zinc complexes,
1H NMR spectroscopy. The structures of
all six complexes are confirmed by single-crystal X-ray
crystallographic studies.
