Abstract
The title molecule, C60H70N2O4Si8, lies on an inversion center. In the asymmetric unit, one of the phenyl rings is disordered over two sets of sites with refined occupancies 0.58 (2) and 0.42 (2). In addition, in two substitution sites of the terminal dimethyl(vinyl)silyl unit, a methyl group and the vinyl group are disordered over the same site with refined occupancies 0.523 (13) and 0.477 (13).
Highlights
One of the phenyl rings is disordered over two sets of sites with refined occupancies 0.58 (2) and
In two substitution sites of the terminal dimethyl(vinyl)silyl unit, a methyl group and the vinyl group are disordered over the same site with refined occupancies
R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger
