“…CsAlTe 3 ,33 the only exception, is located on the quasi binary section Al 2 Te 5 34‐ M 2 Q . It represents a ternary alkali metal chalcogenoaluminate with a close relationship to Cs 2 Ga 2 Q 5 and to RbBSe 3 35. It features five‐membered rings, which form spiro‐cyclic units with triel atoms as spiro center and the chalcogen atoms in oxidation states –I and –II.…”

“…134 MBSe 3 (M = Rb, Cs, Tl) are the first known boron selenium compounds to contain polymeric anionic chains of composition [BSe 3 ] Ϫ n formed by spirocyclically fused nonplanar five-membered B 2 Se 3 rings in which the boron atoms are in tetrahedral BSe 4 coordination. 135 Cs 4 Ti 3 Se 13 is composed of infinite one-dimensional 1 ∞ [Ti 3 Se 13 ] 4Ϫ chains hexagonally close packed along the [100] direction. In between the chains are the Cs ϩ cations.…”

“…In Figure 3 the unit cell of Rb 2 B 2 Se 7 is shown in the direction along [001].Besides these two variations of polymeric anionic chains another type of one-dimensional anion is observed in selenoborate chemistry: its composition is [(BSe 3 ) ± ] n[7], having the lowest chalcogen content in comparison to the present [Anorg. In the perseleno-selenoborates M 2 B 2 Se 7 (M = Rb, Tl) these rings occur in the ratio of 1 : 1 while every third ring in M 3 B 3 Se 10 (M = Cs, Tl) is a tetraselenadiborolane ring system in chair conformation.…”

The perseleno-selenoborates Rb 2 B 2 Se 7 and Cs 3 B 3 Se 10 were prepared from the metal selenides, amorphous boron and selenium, the thallium perseleno-selenoborates Tl 2 B 2 Se 7 and Tl 3 B 3 Se 10 directly from the elements in evacuated carbon coated silica tubes by solid state reactions at temperatures between 920 K and 950 K. All structures were refined from single crystal X-ray diffraction data. The isotypic perseleno-selenoborates Rb 2 B 2 Se 7 and Tl 2 B 2 Se 7 crystallize in the monoclinic space group I 2/a (No. 15) with lattice parameters a = 12.414 (3) A Ê , b = 7.314(2) A Ê , c = 14.092(3) A Ê , b = 107.30(3)°, and Z = 4 for Rb 2 B 2 Se 7 and a = 11.878(2) A Ê , b = 7.091(2) A Ê , c = 13.998(3) A Ê , b = 108.37(3)°with Z = 4 for Tl 2 B 2 Se 7 . The isotypic perselenoselenoborates Cs 3 B 3 Se 10 and Tl 3 B 3 Se 10 crystallize in the triclinic space group P1 (Cs 3 B 3 Se 10 : a = 7.583(2) A Ê , b = 8.464(2) A Ê , c = 15.276(3) A Ê , a = 107.03(3)°, b = 89.29(3)°, c = 101.19(3)°, Z = 2, (non-conventional setting); Tl 3 B 3 Se 10 : a = 7.099(2) A Ê , b = 8.072(2) A Ê , c = 14.545(3) A Ê , a = 105.24(3)°, b = 95.82(3)°, c = 92.79(3)°, and Z = 2). All crystal structures contain polymeric anionic chains of composition ([B 2 Se 7 ] 2± ) n or ([B 3Se 10 ] 3± ) n formed by spirocyclically fused non-planar five-membered B 2 Se 3 rings and six-membered B 2 Se 4 rings in a molar ratio of 1 : 1 or 2 : 1, respectively. All boron atoms have tetrahedral coordination with corner-sharing BSe 4 tetrahedra additionally connected via Se±Se bridges. The cations are situated between three polymeric anionic chains leading to a nine-fold coordination of the rubidium and thallium cations by selenium in M 2 B 2 Se 7 (M = Rb, Tl). Coordination numbers of Cs + (Tl + ) in Cs 3 B 3 Se 10 (Tl 3 B 3 Se 10 ) are 12(11) and 11(9).Synthesen und ro È ntgenographische Charakterisierung von Rb 2 B 2 Se 7 , Tl 2 B 2 Se 7 , Cs 3 B 3 Se 10 und Tl 3 B 3 Se 10 : Neue Perseleno-selenoborate mit polymeren Bor-Selen-Anionenketten b = 89,29(3)°, c = 101,19(3)°, Z = 2 (unkonventionelle Aufstellung); Tl 3 B 3 Se 10 : a = 7,099(2) A Ê , b = 8,072(2) A Ê , c = 14,545(3) A Ê , a = 105,24(3)°, b = 95,82(3)°, c = 92,79(3)°, Z = 2).

Alle Boratome sind tetraedrisch koordiniert, wobei zusa È tzlich zur Eckenverknu È pfung benachbarte BSe 4 -Tetraeder u È ber Diselenidbru È cken miteinander verbunden sind. Die Rb + -und Tl + -Ionen im M 2 B 2 Se 7 (M = Rb, Tl) sind neunfach durch Selenatome, die drei unterschiedlichen Anionenstra È ngen angeho È ren, koordiniert.
