Macrocyclic dioxadiaza from the reaction of the (1,8-diamino-3,6-dioxaoctane)copper(II) cation with formaldehyde and the carbon acids nitroethane or diethylmalonate
摘要:
New square-planar copper(II) complexes of 13-membered dioxa diaza macrocyclic ligands, (12-methyl-12-nitro-4,7-dioxa-1,10-diazacyclotridecane)copper(II), [Cu(L-1)](2+); and (12,12-dicarboxyethyl-4,7-dioxa-1,10-diazacyclotridecane)copper(II), [Cu(L-2)](2+); with perchlorate, hexafluorophosphate and tetrachlorozincate as counter ions have been prepared from the one-pot template condensation reaction of formaldehyde and 1,8-diamino-3,6-dioxaoctane with the carbon acids nitroalkane or diethylmalonate in the presence of the copper(II) ion. Elemental analyses, FTIR, UV-Vis, conductometric, cyclic voltametry and magnetic measurements have been used to, characterize the copper(II) complexes of these dioxa-diaza macrocycles.
