ABSTRACT
The
utilization of 2,6-bis(imidazo[1,5-a]pyridin-3-yl)pyridine (bipp)
and 3-(pyridin-2-yl)imidazo[1, 5-a]pyridine (pip) in the compounds of manganese(II) and
copper(I) ions is presented. Two complexes, [Mn(bipp)(SO4)(H2O)]n (1) and [Cu(pip)2]ClO4 (2), were prepared with different characteristics in structure. Compound 1 exhibits
a one-dimensional chain topology, and 2 is a homoleptic Cu(I) complex. The dc magnetic susceptibility investigations reveal the antiferromagnetic (AF) MnII···MnII interactions in complex 1. The catalytic activity of compound 2 toward ketalization reactions was
studied. Complex 2 exhibits high
activity for the ketalization transformations
of aliphatic ketones.
