Shrinkage Effect

The molecular structure of trimethylindium has been redetermined by vapor phase electron diffraction. The independent structural parameters assuming three-fold axial symmetry based on the rg distances and their estimated uncertainties (2σ) are r(InC) = 209.3 ± 0.6 pm, r(CH) = 114 ± 3 pm, and < HCIn = 112.7 ± 0.8°. A slight nonplanarity (3.0 ± 2.5°) was attributed to a shrinkage effect in [Formula: see text] of 0.4 pm. The analysis was insensitive to the rotational position of the methyl groups relative to the InC3 frame. The root mean square amplitudes were not accurate due to a problem with the indium phase factor.
