between 5 and Zn(OAc)2·2H2O gives both the coordination polymer [2Zn2(OAc)4(5)·2H2O}n] and the discrete complex [Zn2(OAc)4(5)2]. Although the zig-zag form of the polymer chain in [2Zn2(OAc)4(5)·2H2O}n] mimics those in [Zn2(OAc)4(L)}n] (L = 1, 2 or 3), packing interactions differ and the wider separation of the chains in a sheet results in the incorporation of water molecules in the lattice. π-Stacking
