Abstract

The compounds tert-butyl-arsenium(III) tri - chlorido-bis[trichlorido- titanium(IV)], (C₄H₁₂As)[Ti₂Cl₉] or [^tBuAsH₃][Ti₂(-Cl)₃Cl₆], (II), and bis-[bromido-triphenyl-arsenium(V)] di - bromido - oxido-bis-[tribromido-titanium(IV)], (C₁₈H₁₅AsBr) ₂[Ti₂Br₈O] or [Ph₃AsBr] ₂[Ti₂(-O)(-Br)₂Br₆], (III), were obtained unexpectedly from the reaction of simple arsane ligands with Ti ^IV halides, with (II) lying on a mirror plane in the unit cell of the space group Pbcm. Both compounds contain a completely novel ion, with [ ^tBuAsH₃]⁺ constituting the first structurally characterized example of a primary arsenium cation. The oxide-bridged titanium-containing [Ti₂(-O)(-Br)₂Br₆] ^2- dianion in (III) is also novel, while the bromido-triphenyl- arsenium(V) cation is structurally characterized for only the second time.
