The reactions of gallium metal with (p-MeOC(6)H(4))(3)AsI2 and Et(3)AsI(2); Isolation of a novel gallium(II) arsine complex with a gallium-gallium bond and the X-ray crystal structures of GaI3[(p-MeOC(6)H(4))(3)As] and Ga2I4(AsEt(3))(2)

The reactions of (p-MeOC(6)H(4))(3)AsI2 and Et(3)AsI(2) with gallium metal powder produce the metal complexes GaI3[(p-MeOC(6)H(4))(3)As] and Ga2I4(AsEt(3))(2), respectively; the latter represents a unique example of a gallium-tertiary arsine complex containing a gallium-gallium bond, and both structures illustrate the subtle effect of the organic substituent on the arsenic atoms.
