Effects on the magnetic interaction caused by molecular recognition in complexes of 1,2-azole-based oxamate and [Cu(bpca)]⁺ units

Abstract

This work explores the magneto-structural relationships and crystal engineering in five copper(II) complexes of formulas [Cu(bpca)(H2L1)]n·n(CH3)2SO·3nH2O (1), [Cu(bpca)(H2L1)]n·3nCH3OH (2), [Cu(bpca){Cu(bpca)(H2L1)}(H2L1)]n·0.5n(CH2OH)2·3.5nH2O (3) and [Cu(bpca){Cu(bpca)(H2L1)}]n(NO3)n·2n(CH2OH)2·nH2O (4) and [{Cu(bpca)}2L2]·2H2O·0.33(CH2OH)2 (5) [Hbpca = bis(2-pyridylcarbonyl)amide,...
