Abstract:
We describe some copper(II) complexes with tridentate anionic
Schiff bases, L–, derived from the monocondensation of
some 5-substituted salicylaldehydes (5-G-salH, G = H, NO2
and OMe) with ethylenediamine (en) or 1,3-diaminopropane
(tn). Mononuclear [CuL(py)]+, dinuclear [Cu2L2]2+ and trinuclear
[Cu3L3(μ3-OH)]2+ compounds have been obtained, and
factors affecting the nuclearity of complexes were investigated
and found to depend on reaction conditions, the nature
of G and the length of the diamine. The crystal structures
of seven representative compounds have been determined.
Magnetic studies on a dinuclear and a trinuclear species
were also carried out, and the results were interpreted on
the basis of the structural data and current superexchange
models
