title: A new class of soluble and stable transition-metal-substituted polyoxoniobate: [Cr2(OH)4Nb10O30]8-.
abstract: Hydrothermal synthesis of [Cr(III)(2)(OH)(4)Nb(10)O(30)](8-) in gram-scale quantities leads to a new polyoxometalate ion composed of two CrNb(6)O(19) 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 μ(4)-O atoms. Electronic transitions are calculated using density functional theory and compare well with the measured UV-Vis spectra.
