The use of the binary “blend” of MeCO2/pdmH2 ligands (pdmH2 = pyridine-2,6-dimethanol) in copper(II) chemistry has provided access to a compound consisting of discrete linear CuII3 and cubane CuII4 clusters. The complicated magnetic behavior of the CuII3 + CuII4 complex was clarified and interpreted through the designed synthesis of the individual CuII4 component; a unique 1D (CuII5)n compound containing a CuII3 subunit, which is structurally similar to the trinuclear cluster in the CuII3 + CuII4 compound, was also isolated and structurally characterized.
