In this study, the utilization of bipp and pip molecules as ligands for manganese and copper ions was demonstrated. Two complexes with different structures, [Mn(bipp)(SO4)(H2O)]n (1) and [Cu(pip)(2)]ClO4 (2), were synthesized. Compound 1 showed a one-dimensional chain structure, while compound 2 exhibited a homoleptic Cu(I) complex. The research also revealed antiferromagnetic interactions in compound 1 and high catalytic activity for ketalization reactions in compound 2.
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) Mn-II center dot center dot center dot Mn-II 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.
