Hydrothermal synthesis of [CrIII2(OH)4Nb10O30]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 CrIII atoms are located in the centre of the molecule and are bridged by two μ4-O atoms. Electronic transitions are calculated using density functional theory and compare well with the measured UV-Vis spectra.
