V. Izarova, Raisa I. Maksimovskaya, Sabine Willbold, Paul KögerlerThe novel tetrapalladium(II)-containing
polyoxometalate [PdII4(α-P2W15O56)2]16– has been
prepared in aqueous medium and characterized as its hydrated sodium
salt Na16[Pd4(α-P2W15O56)2]·71H2O by single-crystal
XRD, elemental analysis, IR, Raman, multinuclear NMR, and UV–vis
spectroscopy. The complex exists in anti and syn conformations, which
form in a 2:1 ratio, and possesses unique structural characteristics
in comparison with known {M4(P2W15)2} species. 31P and 183W NMR spectroscopy
are consistent with the long-term stability of the both isomers in
aqueous solutions.
