Structure ofcatena-(2-amino-1,3,4-thiadiazolium, 2-amino-1,3,4-thiadiazole bis(μ-iodo)-di-iodo-bismuth(III)

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

“…Bismuth(III), typically regarded as a soft Lewis acid, readily forms complex halobismuthate ions by accepting halide ions (X À ) from multiple donor sources [11,12]. We and others have employed varied halide ion sources in the syntheses of these halobismuthate materials including: alkylammonium halides (e.g., tetrabutylammonium iodide), alkali metal-halides, and haloacids (HCl, HBr, or HI) [1][2][3][4][5][7][8][9][10][13][14][15].…”

“…In general, these systems involve an anionic metal-halide component for which charge balance is provided by an organic cation. Within this family of materials, tremendous structural diversity has been observed as the anionic component may range from discrete mono-or polynuclear species to one or 2-D polymeric species depending the specific reaction conditions employed.Bismuth(III), typically regarded as a soft Lewis acid, readily forms complex halobismuthate ions by accepting halide ions (X À ) from multiple donor sources [11,12].

[Co(phen3)]2[Cu11I15]: a mixed-metal iodocuprate containing the novel [Cu10I15]5− and [Cu12I15]3− clusters

“…The trihalides of the Group 15 elements arsenic, antimony, and bismuth are known to be strong halide ion acceptors [1][2][3] and, thus, they can form numerous complex anions including, at times, heterometallic anions. 4 These complex anions are known to exist in compounds as mononuclear species, discrete polynuclear species, or polymeric anions.…”

“…Furthermore, data from the literature suggest that the size and connectivity of halometallate anions depend on the size and charge density of available counter cations, the stoichiometry of the starting materials, as well as other specific reaction conditions (e.g., solvent and reagent choice). 1,5,6 Halometallates containing metals from other groups are also known, including those based on Sn(II), Ag(I), and Cu(II); and halometallate compounds have been synthesized using a variety of organic counter ions, as well as, more recently, transition metal coordination cations. [5][6][7][8][9][10][11] Among these, the iodocuprates have been extensively investigated; and the work, in particular, of Hartl and co-workers, has resulted in the syntheses and structural characterizations of a large number of copper(I) iodide clusters, including: Cu 5 I 7 .…”

Synthesis and Crystal Structure of [C6H4OCH3NH3]2BiCl5

“…1 Consequently, numerous complex haloanions of bismuth have been formed with a variety of cations, and most of them are constituted by polynuclear anions with different polymerization geometries, where the basic MX6 octahedra share corners, edges, and faces. [2][3][4] In these compounds the metal shows a tendency toward distorted octahedral coordination with observable differences in the Bi-X bond lengths and Bi-X-Bi angles from the mean values characteristics of non-deformed polyhedra.…”
