title: A novel poly(polyoxometalate) built by {Cu9}/{Cu5} clusters and {PW9}/{PW10}/{PW11} lacunary fragments.
abstract: The hydrothermal reactions of [A-α-PW9O34](9-) with CuCl2·2H2O in the presence of ethanediamine (en) and acetate afforded a novel poly(polyoxotungstate) containing different lacunary fragments: monolacunary {α-PW11O39}, dilacunary {α-PW10O37}, trilacunary {B-α-PW9O34}, etc. In addition, a cockhorse-like nona-copper {Cu9} slab is incorporated. Magnetic investigation indicates overall antiferromagnetic interactions in this compound.
