Abstract:A tetranuclear cluster {[(Tp)Fe(CN)(3)]Co(pp)H2O}(2) . [(Tp)Fe(CN)(3)](2) .6H(2)O (1; Tp = hydrotris(pyrazoly)borate, pp = 2,6-bis(N-pyrazolyl)pyridine) and a hexanuclear cluster {[(pzTp)Fe(CN)(3)](2)Co(pp)}2.2H(2)O (2; pzTp = tetrakis(pyrazoly)borate) have been synthesized via rational assembly of the same (ppCo(II))(2+) unit and different tricyanometalate building blocks with varying proportions of sterically hindered groups. Magnetic measurements reveal that 1 exhibits the dominant antiferromagnetic interactions between Fe(III) and Co(II) ions, while 2 exhibits the dominant ferromagnetic interactions.
