Three new binuclear complexes: [(NO)(CN)(4)FeCN-Co(en)(2)] . H2O (1), [(NO)
(CN)(4)FeCN-Co(pn)(2)] . 2H(2)O (2), and [(NO)(CN)(4)FeCN-Co(tn)(2)] . 3H(2
)O (3) (en = ethylenediamine, pn = 1,2-diaminopropane; tn = 1,3-diaminoprop
ane) have been prepared and their properties studies by i.r., u.v. spectros
copy, cyclic voltammetry, and by magnetic measurements.
