Abstract
The compounds tert-butylarsenium(III) tri-mu-chlorido-bis[trichloridotitanium(IV)], (C4H12As)[Ti2Cl9] or [ t BuAsH3][Ti-2(mu-Cl)(3)Cl-6], (II), and bis[bromidotriphenylarsenium(V)] di-mu-bromido-mu-oxido-bis[tribromidotitanium(IV)], (C18H15AsBr)(2)[Ti2Br8O] or [Ph3AsBr](2)[Ti-2(mu-O)(mu-Br)(2)Br-6], (III), were obtained unexpectedly from the reaction of simple arsane ligands with TiIV 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 [ t BuAsH3]+ constituting the first structurally characterized example of a primary arsenium cation. The oxide-bridged titanium-containing [Ti-2(mu-O)(mu-Br)(2)Br-6]2- dianion in (III) is also novel, while the bromidotriphenylarsenium(V) cation is structurally characterized for only the second time.
