Synthesis and characterization of Co(II) and Mn(II) [M3L3] triangles
We report an improved method to make the ligand N,N′ -(pyrazine-2,5-diylbis(methanylylidene))bis(2-(pyridin-2-yl)ethanamine) ( L ) and the subsequent complexation of this ligand to make the triangular metallo-macrocycles [Co 3 L 3 ](ClO 4 ) 6 ·2H 2 O ( C1 ·2H 2 O) and [Mn 3 L 3 ](ClO 4 ) 6 ·3H 2 O (...
