Hydrothermal synthesis of [Cr-2(III)(OH)(4)Nb10O30](8-) in gram-scale quantities leads to a new polyoxometalate ion composed of two CrNb6O19 Lindqvist-type units that are fused via shared faces. The two Cr-III atoms are located in the centre of the molecule and are bridged by two mu(4)-O atoms. Electronic transitions are calculated using density functional theory and compare well with the measured UV-Vis spectra.
