Synthesis, crystal and molecular structure of the first metal complex [Pt(PPh3)22-AsC(C6H2But3)}] derived from an arsaalkyne

Abstract
Treatment of [Pt(PPh3)2(C2H4)] with AsC(C6H2But 3) affords the title compound, the X-ray crystal structure of which shows the arsaalkyne ligand to be η2-ligated; the X-ray crystal structure of the parent arsaalkyne is also reported.
