A noncentrosymmetric chiral Strandberg-type polyoxometalate based material, Cs(4)Mo(5)P(2)O(22), that contains unusual one dimensional chains constructed from [Mo(5)P(2)O(23)](6-) units has been reported. Cs(4)Mo(5)P(2)O(22) shows a moderate SHG response, and is phase-matchable.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
