 Title    Darstellung und Kristallstrukturen von (Ph4P)4Sb8I28 und (Ph4P)Sb3l 10 (Ph = C6H5) Synthesis and Crystal Structures of (Ph4P)4Sb8I28 and (Ph4P)Sb3 l 1 0 (Ph = C6H 5)  
 Abstract    The compounds (Ph4P)4Sb8l 28 (1) and (Ph4P)Sb,Iio (2) were prepared by the reaction of Sbl3 and Ph4PI in acetonitrile (molar ratios 2:1 and 3:1 respectively). The structures of 1 and 2 were determined from single crystal X-ray diffraction data. 1 crystallizes in the triclinic space group P I with a = 1321.7(5), b = 1346.7(5), c = 2201.8(8) pm, a = 104.18(2), ß = 99.92(2), y = 100.33(2)°; 2: monoclinic, C2/c, a = 2371.1(2), b = 745.0(1), c = 2495.1(2) pm, ß = 100.75(1)°. Whereas 1 exhibits isolated SbsI284' ions, the anions of 2 are built up of polymeric chains [Sb3I 10_]x. In both compounds the distorted Sbl6 octahedra are linked by common edges. The Sb—I distances are in the range between 277.4 and 354.8 pm (1) and between 277.4 and 342.4 pm (2). The observed structures do not only depend on stoichiometry. the nature of the counter cations, and the possibility of oligomerisation but also on the wide variety of the Sb—I bond strengths and the different bridges formed by iodine. The lone pair of Sb(III) seems to be predominantly 5s: .

 Abstract    The reaction of Sbl 3 with Me 4 NI, Me ? SI, and Me^NCH^Phl in acetonitrile (molar ratios 2:1) yields (Me 4 N) 4 Sb 8 I 28 (1). (Me,S) 4 Sb K I 28 (2). and (Me,NCH 2 Ph)Sb : I 7 (3), respectively. The struc-tures of 1—3 were determined from single crystal X-ray diffraction data. 1—3 crystallize in the monoclinic space group P2,/«. 2: a -1434.2(3). b -1484.1(4). c = 2102.6(4) pm. ß = 105.4(1)°, Z = 2. 1: a = 1441.7(1), b = 1545.1(1). c = 2117.3(1) pm. ß = 106.4(1)°, Z = 2. 3: a = 1004.4(1). b = 1378.8(1). c = 1899.3(2) pm. ß = 94.2(1)°.

 Title    Bildung von Iodoantimonaten und -bismutaten. Kristallstrukturen von (PhCH2NEt3)4 [Sb6l 2 2 L (PhCH2NEt3)4 [Bi6l 2 2 ] und (Ph4P)3[Bi5I18] Form ation of Iodoantim onates and Bismutates. Crystal Structures of (PhCH 2N E t3)4[Sb6I22], (PhC H 2N Et3)4[Bi6l22] and (Ph4P)3[Bi5I 18]  
 Abstract    The formation and the crystal structures of the title compounds are reported. (PhCH2N E t3)4[Sb6l 22] and (PhCH 2N E t3)4[Bi6l 22] are isotypic and contain a novel [E6I22]4~ anion (E = Sb, Bi). The anion of (Ph4P)3[Bi5I18] consists of a linear chain of five face-sharing [B il6] octahedra.
