    • X-ray crystal structure analysis of 1
    • 2 = 0.1024 (I > 2σ(I)), GOF = 1.026. The overall data quality is limited, as revealed by the R(int)value of 0.1312, because the crystal was small and only weakly diffracting. No time dependency of the quality within the measurement has been observed. Attempts to obtain better crystals have not been successful

    • One referee suggested that the reason for the Ge-Ge p bonding could be the slightly larger electronegativity of Ge compared with Ga. We checked this by calculating the silicon and tin homologues of 1M. The electronegativities of Si (1.7) and Sn (1.7) are smaller than that of Ga (1.8) but the electronic structure of the group-14 homologues showed also Si-Si and Sn-Sn p bonding, respectively
