36. 3 was the first structurally characterized compound of this type: B. Beagley, S. M. Godfrey, K. J. Kelly, S. Kungwankunakcorn, C. A. McAuliffe, R. G. Pritchard, Chem. Commun. 1996, 2179-2180. The Ga-Ga bond of 242.8 pm in this compound is considerably shorter than that in 2 (249 pm). This is in agreement with strengthening of the Ga-donor interaction and resulting weakening of the Ga-Ga bond in 2.
