challenges to overcome by chemist thinking about new synthetic procedures yielding YBACUO and related superconducting phases, lies on the control of the stoichiometry and sample homogeneity of the precursors. We describe here an alternative method involving bimetallic YCu and BaCu coordination compounds. Superconducting single phases showing an homogeneous distribution of low-sized particles can be
