Synthesis and molecular structure of an unusual –Ga–Ga–Ga– linked organometallic

Abstract

Reaction of [(2,4,6-Prⁱ₃C₆H₂)₂C ₆H₃]GaCl₂ with P(SiMe₃)₃ affords the unusual organometallic compound [(2,4,6-Prⁱ₃C₆H₂)₂C ₆H₃]Ga{H₂PGa(H)PH₂}G a[C₆H₃(C₆H₂- Prⁱ₃-2,4,6)₂] 1 characterized by multinuclear NMR, complete (C, H, Ga and P) elemental analyses, IR spectroscopy and single crystal X-ray diffraction; 1 is significant as it contains a rare Ga–Ga–Ga [2.5145(13) and 2.7778(14) Å] linkage even as its formation is facilitated by the unusual stripping of the sterically demanding m-terphenyl ligand from the central gallium atom.
