The dimeric, zirconium‐sandwiching compound K 4 H 6 [Zr 4 (OH) 6 (CH 3 COO) 2 (α‐PW 10 O 37 ) 2 ] · 23H 2 O ( 1 ) was obtained by the reaction of lacunary [PW 11 O 39 ] 7– and ZrCl 4 in a 1 M potassium acetate buffer. It was characterized by elemental and thermogravimetric analysis, X‐ray crystallography, solution 183 W NMR, FTIR, and UV spectroscopy, and cyclic voltammetry (CV). All the studies indicate that compound 1 is stable both in the solid state and in solution. The cyclic voltammograms indicate good electrocatalytic activity in the reduction of nitrite.
