Compounds (IV) and (VI) (yields are given in gram) are characterized by powder and single crystal XRD and FTIR, UV/VIS, and luminescence spectroscopy. (IV) crystallizes in the monoclinic space group P21/n with Z = 4 and (VI) in the triclinic space group P1 with Z = 2. Both compounds exhibit three-dimensional frameworks. In (IV) [Ru(bipy) 3 ] 2+ ions are located between infinite double chains formed by adjacent [H2W12O40] 6-Keggin anions linked through {KO7} and {NaO6} polyhedra, while in (VI) the [Ru(pzc)3]anions are confined by layered networks of [SiW12O40] 4clusters connected by K + ions. Compound (IV) shows strong luminescence at 604 nm in the solid state at room temperature. -(YAN*, B.; HODSDON, S. A.; LI, Y.-F.; CARMICHAEL, C. N.; CAO, Y.; PAN, W.-P.; J.
