Synthesis and characterization of new heterometallic cyanido complexes based on [Co(CN)6]~(3-) building blocks: crystal structure of [Cu2(N-bishydeten)2Co(CN)6] 3H2O having a strong antiferromagnetic exchange

摘要

A tetradentate N- and O- donor, N,N-bis(2-hydroxyethyl)-ethylenediamine, (N-bishydeten), has been employed to synthesize four new heterometallic cyanido complexes, [Ni2(N-bishydeten)2Co(CN)6]·3H2O (CI), [Cu2(N-bishydeten)2Co(CN)6]·3H2O (C2), [Zn2(N-bishydeten)2Co(CN)6]-5H2O (C3) and K[Cd(N-bishydeten)-Co(CN)6M.5H2O (C4). Characterization of the complexes was performed using IR and EPR spectroscopy (for C2), thermal analysis and elemental analysis techniques. The crystal structure of C2 was determined by the X-ray single crystal diffraction technique.
