Abstract : Prior to 1986, there were no published examples of gallium-arsenic compounds containing a single As3Ga or Ga3A unit. However, during that year two compounds of the first type having three coordinate Ga and three coordinate As were reported, (R2As)3Ga(R=Mes(1)Bu(+2)). We now report the isolation and structure of a compound of the second type having, in this initial case, four-coordinate Ga and three- coordinate As, (thf) Br Ga As (thf = tetrahydrofuran) (1). The reaction of (Me3Si)3As3 with GaBr3, which affords the (Br2Ga)3As species found in (1), appears to be the first reported of a tri (silyl) arsine being utilized to form the Ga As linkage, and it further demonstrates the importance of siliylarsines in the area of preparative gallium arsenic chemistry. Keywords: Gallium, Arsenic.
