    • NMR (1H at 500MHz, 13C at 125 MHz, and 29Si at 99 MHz) spectra in ppm were obtained on a Varian model Unity INOVA. MALDI-TOF MS was performed with a Voyager DE RP. XRD was performed on a Rigaku RAXIS RAPID imaging plate area detector with graphite monochromated Cu Kκ radiation. Indexing was performed from three oscillations exposed for 36 s. The crystal-to-detector distance was 127.4 mm. The exposure rate was 12.0 s/deg. Readout was performed in the 0.100 mm pixel mode. The structure was solved by direct methods and expanded using Fourier techniques. Some non-hydrogen atoms were refined anisotropically, while the rest were refined isotropically. Hydrogen atoms were refined using the riding model. All calculations were performed using Crystal Structure crys-tallographic software except for refinement performed using SHELXL-97.
