The reaction of [Cu(valen)] with Tb(NO3)3 and (Bu3NH)3- [W(CN)8] affords two types of crystals: [{W(CN)8}Cu(valen)- Tb(OH2)5]*2H2O (1, a discrete trinuclear complex) and [{W(CN)8}Cu(valen)Tb(OH2)4]*CH3CN*H2O (2, an infinite zig-zag chain), both compounds showing slow relaxation of the magnetization (H2valen is the Schiff base resulting from the reaction of o-vanillin with 1,2-ethanediamine).
