A novel tetranuclear iodoargentate(I) ion, [Ag4I8]4−, with a cubane-type core

Excitonic Bands in the Optical Absorption Spectra of (Bu4N)CuBr2, (Et4N)2Cu2Br4, (Pr4N)2Cu4Br6, (Bu4N)2Cu2I4, (Me4N)Cu2I3, (Pr4N)4Ag4I8, (Me4N)Ag2I3, (Et4N)Ag2Br3, and Similar Compounds

“…(Me4N)Cu2I3 and (Me4N)Ag2I3 were prepared by using Me4NI and MX (M=Cu, Ag) in a ratio 1:2 [19], instead of 1:1 [21,24], The structure of the crystals was identified by Weissenberg diagrams or by a complete X-ray-diffraction crystal structure solution. In the case of Me4NAg2l3, the structure was found to be little different from that in the literature [23], The space group Pcmn, a= 10.066, b = 7.426, c= 17.739 A, V= 1326 A ' [19] was found. Thin deposits (of these compounds as well as of the corresponding conventional compounds) are mainly prepared by translational or rotational rubbing the crystals on quartz plates (see [9] and refs therein).…”

“…Crystals of (Pr4N)4Ag4Ig contains discrete Ag4Ig4_ anions with a cubane-type core (0-dimensional) [23]. Crystals of (Me4N)Ag2I3 contain infinite polymeric anions (A g2I3_ )oc/oc ( 1-dimensional system) [19,24].…”

“…The preparations, crystals structures and electronic band structures of these compounds are described in [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. To avoid oxidations of Cu(I) materials, a small amount of H3PO2 was added to the mother solutions be fore precipitation of crystals [19].…”

Syntheses, Crystal Structures, and Photocatalytic Properties of Bromoargentates Induced by Transition‐Metal–phen Complex Cations

“…To date, a large number of silver(I) iodine [Ag m I n ] ( n – m )– anions ranging from discrete clusters (0D) to one‐dimensional (1D) chains, two‐dimensional (2D) layers, and three‐dimensional (3D) frameworks have been reported and characterized. Examples of iodoargentate anions include the 0D clusters [Ag 4 I 8 ] 4– , [Ag 14 I 16 ] 2– , and [Ag 14 I 22 ] 8– ; the 1D chains [Ag 2 I 3 ] – , [Ag 2 I 4 ] 2– , [Ag 3 I 5 ] 2– , [Ag 4 I 6 ] 2– , [Ag 5 I 7 ] 2– , [Ag 5 I 9 ] 4– , [Ag 6 I 9 ] 3– , and [Ag 11 I 15 ] 4– ; the 2D layers [Ag 2 I 3 ] – , [Ag 4 I 5 ] – , [Ag 5 I 6 ] – , [Ag 6 I 8 ] 2– , and [Ag 6 I 9 ] 3– ;[3c], [15b], and the 3D networks [AgI 2 ] – , [Ag 2 I 4 ] 2– , [Ag 4 I 6 ] 2– , [Ag 5 I 6 ] – , [Ag 5 I 7 ] 2– , [Ag 9 I 13 ] 4– , [Ag 12 I 16 ] 4– , [Ag 13 I 17 ] 4– , and [Ag 14 I 16 ] 2– , . The structures and dimensionalities of iodoargentates are influenced by various factors, including pH value, solvent, and reaction temperature in the synthesis process and structure‐directing agents (SDAs).…”
