Abstract: A new 1D ladder-like chain polyoxotungstate K6[Mn2(H2O)8(H2W12O42)]·14.5H2O(1) was synthesized in aqueous solution and characterized by elemental analysis, IR spectroscopy, TG analysis, UV, CV and single crystal X-ray diffraction. The interesting characteristics of compound 1 show that the paradodecatungstate [H2W12O42]10- anions are linked by Mn2+ ions forming a ladder-like one-dimensional chainlike structure, which is connected by K+ ions a 3D framework. The oxidation states of W and Mn sites in this compound are determined to be +6 and +2, respectively.

Key words: Polyoxometalates, Crystal structure, Manganese, Paradodecatungstate
