Octadecanuclear cluster or 1D polymer with [{ML}(2)Nb(CN)(8)](n) motifs as a function of {ML} (M = Ni(II), n=6; M = Mn(II), n = infinity; L = macrocycle)
A nanosized octadecaheteronuclear aggregate, [{NiL2}(12){Nb(CN)(8)}(6)(H2O)(6)], and a 1-D coordination polymer, [{MnL1}(2){Nb(CN)(8)}(H2O)](infinity), have been obtained by self-assembly between the octacyanometalate {Nb(CN)(8)}(4-) and {ML}(2+) complexes. The dimensionality of the supramolecular architectures was found to be controlled by the {ML} module for which the equatorial coordination sites are blocked by a macrocyclic ligand. The crystal structures and magnetic properties for both the compounds are described.
