Two‐ and Three‐Dimensional Frameworks Constructed From Bicapped Keggin Clusters

The novel two‐ and three‐dimensional solid materials [Cu(en)2(H2O)]{PMoVI8VIV6O42[Cu(en)2][Cu0.5(en)]3}·5.5H2O and H3{VVMoVI8VIV6O42[Cu(en)2]4}[MoO4]2·14H2O (en = ethylenediamine) have been hydrothermally assembled and structurally characterized. Both networks are based on mixed Mo/V bicapped Keggin clusters interconnected through the transition metal complex moieties. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
