Abstract

The preparation of platinum(II) complexes of the types [PtCl2{Y(CH2CH2O) x CH2CH2Y}] (Y: imidazol-1-yl, im; pyrazol-1-yl, pz or benzimidazol-1-yl, bim) and [PtI2{im(CH2CH2O) x CH2CH2im}] with varying ligand backbone length (x between 0 and 3) is described. A new bis(pyrazol-1-yl) polyether compound, pz(CH2CH2O)2CH2CH2pz, is reported. Spectroscopic characterization of the complexes is discussed. Two crystal structures of the general formula [PtCl2{im(CH2CH2O) x CH2CH2im}] (x is 1 or 3) are also reported.
