A new Cu/Zn carboxylato-bridged 1D polymer: Direct synthesis, X-ray structure and magnetic properties

► A new Cu/Zn complex with acetate and ammonia was isolated. ► 'Paddlewheel' copper acetate dimers and monomeric zinc complex units alternate forming a 1D polymer. ► High-field EPR spectra showed both the exchange-coupled copper pair and non-interacting copper(II) ions. ► The presence of the latter species was explained as an effect of zinc atoms occupying a fraction of the copper sites.
