Abstract
The bond lengths in the halides of the fourth, fifth, and sixth group elements are in general considerably shorter than the sums of the corresponding Pauling-Huggins covalent radii. This discrepancy appears to be partially resolved by the introduction of a correction for the partial ionic character of the bonds; however, large disparities remain for the second row fluorides, while for the heavier halides the agreement is not precise. For the bromosilanes considered in this paper, the Si-Br distances are found to be 2.16 ± 0.03 Å., 0.06 Å. shorter than the distance calculated by Schomaker and Stevenson. The bond-angle values reported here are all approximately tetrahedral with the exception of that for F-Si-F in SiF_2Br_2, which seems to be decidedly less than tetrahedral. This value may be in error, however, as noted below.
