[Ru(2,2′-bipy)3]2[Bi4I16]:: A bimetallic inorganic-organic complex consisting of a d-metal coordination cation and a polynuclear iodobismuthate anion

The crystal structure of [Ru(2,2'-bipy)(3)](2)[Bi4I16] (2,2'-bipy = 2,2'-bipyridine) contains the photochemically active coordination cation [Ru(2,2'-bipy)(3)](2+) and the large, polynuclear [Bi4I16](4-) anion. [Bi4I16](4-) consists of four edge-sharing BiI6 octahedra and is derived from the neutral, semiconductor BiI3 by uptake of I-. The title con pound is a rare example of a mixed-metal halobismuthate material [crystal data C60H48Bi4I16N12Ru2: triclinic, P (1) over bar, a = 12.2963(7) angstrom, b = 14.0147(8) angstrom, c = 14.7234(8) angstrom, alpha = 70.1900(1)degrees, = 69.2010(1)degrees, gamma = 72.6570(1)degrees].
