[Ag70(PW9O34)2(tBuCC)44(H2O)2]8+: ionothermal synthesis of a silver cluster encapsulating lacunary polyoxometalate ions†
Abstract
A silver alkynyl cluster containing a Ag70 shell and two lacunary [PW9O34]9− templating ions was synthesized by an ionothermal approach. Fast core–shell electronic communication between silver(I) centers and polyoxometalates was verified via cyclic voltammetry studies in [BMIm]BF4.
