Synthesis and Crystal Structure of Tris(dimesitylarsino)gallane, a Monomeric Tricoordinate Gallium-Arsenic Compound.

Abstract

The gallium-arsenic bond, in polymeric form is expected to exhibit anisotropic conductivity by virtue of an extended p-pi system, isoelectronic with polyacetylene. Four mono-, bis-, and trisarsinogallanes were prepared from the reaction of lithium dimesitylarsenide with gallium chlorides. One of these, tris(dimesitylarsino) gallane, (Mes2As)3Ga(1), was characterized by single crystal x-ray analysis and shown to be the first example of a monomeric tricoordinate gallium-arsenic compound. Orange crystals of 1 belong to the triclinic system space group P1. The gallium atom is bonded to the three arsenic atoms in a trigonal planar configuration. The color of 1 is the result of tailing of a 276 nm CT band into the visible.
