The new Fe(III) complexes with isosceles or equilateral configurations showed atypical magnetic behaviour with a magnetic susceptibility which does not obey the Curie-Weiss law. The experimental data were fitted by using the Heisenberg-Dirac-van Vlec

It has been shown by x-ray structural examination and IR spectroscopy that conformations of diphenylacetylbenzo-12-crown-4 in which the lone pairs of oxygen are oriented on opposite sides of the plane of the macrocycle are stabilized in the crystal a
