Abstract

Abstract: A new heteropolycomplex, K₆H₃[ZnW₁₁ O₄₀ Al]·9.5H₂O was prepared and characterized by means of elemental analysis, IR, UV spectroscopy, ²⁷Al NMR , electrochemistry and X ray crystallography. The crystal of K₆H₃[ZnW₁₁ O₄₀ Al]·9.5H₂O is cubic, space group Fm-3m , with lattice constants a=b=c =2.144 8(2) nm, V =9.866(2) nm³, Mo radiation, R =0.057 8 for 497 independent data with [ I>2δ(I) ]. The anion is of α type Keggin structure with C_s symmetry.

Key words: Lacunary, Keggin structure, Synthesis, ²⁷Al NMR
