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.
