Synthesis and Crystal Structures of [P(C6H5)4][1-(NH3)B10H9] and Cs[(NH3)B12H11] · 2CH3OHThe reduction of [1-(NO2)B10H9]2- with aluminum in alkaline solution yields [1-(NH3)B10H9]- and by treatment of [B12H12]2- with hydroxylamine-O-sulfonic acid [(NH3)B12H11]- is formed. The crystal structures of [P(C6H5)4][1-(NH3)B10H9] (triclinic, space group P1, a = 7.491(2), b = 13.341(2), c = 14.235(1) Å, α = 68.127(9), β = 81.85(2), γ = 86.860(3)°, Z = 2) and Cs[(NH3)B12H11] · 2CH3OH (monoclinic, space group P21/n, a = 14.570(2), b = 7.796(1), c = 15.076(2) Å, β = 111.801(8)°, Z = 4) reveal for both compounds the bonding of an ammine substituent to the cluster anion.
Notes:
Die Reduktion von [1-(O2N)B10H9]2- mit Aluminium in alkalischer Lösung ergibt [1-(NH3)B10H9]-, bei der Umsetzung von [B12H12]2- mit Hydroxylamin-O-sulfonsäure bildet sich [(NH3)B12H11]-. Die Röntgenstrukturanalysen an [P(C6H5)4][1-(NH3)B10H9] (triklin, Raumgruppe P1, a = 7,491(2), b = 13,341(2), c = 14,235(1) Å, α = 68,127(9), β = 81,85(2), γ = 86,860(3)°, Z = 2) und Cs[(NH3)B12H11] · 2CH3OH (monoklin, Raumgruppe P21/n, a = 14,570(2), b = 7,796(1), c = 15,076(2) Å, β = 111,801(8)°, Z = 4) beweisen, daß in beiden Fällen ein Ammin-Substituent am Clusteranion vorliegt.
