The title compound, [(C5H12N)4][V10O26(OC2H5)2] consisting of a [V10O26(OC2H5)2]4– polyanion and four protonated piperidinium [C5H12N]+ was synthesized and characterized by elemental analyses, spectroscopic (IR, UV-vis and ESR) studies and single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21/n and Z = 2, with a = 10.628(2) capital A, ring ,b = 12.983(2) capital A, ring , c = 16.160(3) capital A, ring , and beta = 90.74(3). Least-squares refinement gave a final R factor of 0.0559 for 4024 unique reflections having I >2sigma(I). A three-dimensional supramolecular arrangement of the polyanion and piperidinium cations in the crystal lattice is generated by hydrogen bonds. In contrast with other anionic decavanadates, there are two ethoxy groups bridging the outmost vanadium atoms in the title compound. The coordinated nature of the ethoxy-bridge is the first example among the reported decavanadates. The cyclic voltammetry behaviour of the compound is preliminarily investigated.
