[Pd(NH3)(4)](3)(Mo7-xWxO24)center dot 6H(2)O crystals with different Mo/W ratios have been formed as a result of the crystallization of a mixture of Na6W7O24, Na6Mo7O24, and [Pd(NH3)(4)](NO3)(2) aqueous solutions. Ten crystals with 0.8 <= x <= 3.4 have been studied. In the polyanion, Mo and W atoms occupy preferred sites rather than are distributed statistically. The crystallographic characteristics of [Pd(NH3)(4)](3)(Mo3.6W3.4O24)center dot 6H(2)O are found to be as follows: a = 17.4294(2) angstrom, b = 28.9215(4) angstrom, c = 30.4435(4) angstrom, sp. gr. Ibca, V = 15346.1(3) angstrom(3), and Z = 16. The anion packing in the structure has been analyzed. It is shown that anions are arranged into a pseudohexagonal motif. The products of thermal decomposition in H-2 atmosphere have been studied. It is shown that a mixture of solid substitutional solutions based on Pd and Mo(W) lattices is formed at 800 degrees C.
