The synthetic investigation of the Cu II /maleamate(−1) ion (HL − )/N,N′,N′′-chelate general reaction system has allowed access to compounds [Cu 2 (HL) 2 (bppy) 2 ](ClO 4 ) 2 ·H 2 O (1·H 2 O), [Cu(HL)(bppy)(ClO 4 )] (2) and [Cu(HL)(terpy)(H 2 O)](ClO 4 ) (4) (bppy=2,6-bis(pyrazol-1-yl)pyridine, terpy=2,2′;6′,2′′-terpyridine)...
A systematic investigation of the reactions of Cu(ClO 4 ) 2 ·6H 2 O with maleamic acid (H 2 L) in the presence of 2,2′-bipyridine (bpy) has been carried out. The chemical and structural identity of the products depends on the solvent, the absence or presence of external hydroxides in the reaction mixture and the molar ratio of the reactants. Various reaction schemes...
