Description / Table of Contents:
Crystal Structures of (PPh4)2[1-(SCN)B10H9] and (AsPh4)2[1,10-(SCN)2B10H8]By reaction of [B10H10]2- with (SCN)2 in dichloromethane mixtures of thiocyanato-hydro-closo-decaborates are formed. The crystal structures of (PPh4)2[1-(SCN)B10H9] (monoclinic, space group P 21/a, a = 20.245(2), b = 10.434(9), c = 22.235(3) Å, β = 90.951(10)°, Z = 4) and (AsPh4)2[1,10-(SCN)2B10H8] (triclinic, space group PP1, α = 10.598(2), b = 13.057(3), c = 19.902(3) Å, α = 104.37(2), β = 91.725(11), γ = 110.35(2)°, Z = 2) reveal for both compounds the bonding of the SCN substituents via the S atom.
Notes:
Bei der Umsetzung von [B10H10]2- mit (SCN)2 in Dichlormethan entstehen Gemische aus Thiocya nato-hydro-closo-decaboraten. Die Röntgenstrukturanalyse an (PPh4)2[l-(SCN)B10H9] (monoklin, Raumgruppe P21/a, a = 20,245(2), b = 10,434(9), c = 22,235(3) Å, β = 90,951(10)°, Z = 4) und (AsPh4)2[1,10-(SCN)2B10H8] (triklin, Raumgruppe P1, a = 10,598(2), b = 13.057(3), c = 19,902(3) Å, α = 104,37(2), β =91,725(11), γ =110,35(2)°, Z = 2) beweist in beiden Fällen die Bindung der SCN-Substituenten über das S-Atom.
