- Abstract
Three new cyanide-bridged heterobimetallic complexes {[Cu(L)]2[Cr(CN)5(NO)]}ClO4·2H2O (1), {{[Cu(cyclam)][Fe(CN)5(NO)]}·H2O}n (2), {{[Cu(cyclam)]3[Cr(CN)5(NO)]2}·CH3OH·4H2O}n (3) (L=2,12-dimethyl-3,7,11,17-tetraazabicyclo [11.3.1] heptadeca-1 (17), 13, 15-triene, cyclam=1,4,8,11-tetraazacyclodecane) have been successfully assembled from the pentacyanometalates and two copper(II) compounds and characterized by elemental analysis, IR spectroscopy and X-ray structure determination. X-ray structural analysis revealed that the Complex 1 is a cationic trinuclear CrCu2 entity with the positive charge balanced by ClO4− ion, while complexes 2 and 3 were structurally characterized showing a 1D chain. The magnetic properties of the reported cyanide-bridged complexes have been experimentally studied and theoretically simulated, disclosing the ferromagnetic interaction between the Cr(I) ion and the Cu(II) ion through the cyanide bridge.
