The mixed-valence coordination polymer [Cu(S2CNPr2)2]2[ClO4] containing alternating square-planar Cu(II) and Cu(III) centres

The mixed-valence coordination polymer, [Cu(S2CNPr2)2]2[ClO4], containing both square-planar Cu(II) and Cu(III) centres, has been prepared and crystallographically characterised. In the solid-state it consists of a chain of alternating Cu(II) and Cu(III) centres held together by intermolecular Cu–S interactions, while the perchlorate anions are not metal coordinated. For comparison the crystal structure of [Cu(S2CNPr2)2]2 has been re-determined at 150 K.
