Abstract: The crystal structure of four 1-oxo-4-(substituent)-1-phospha-2,6,7-trioxacyclo(2,2,2) octane have been determinded by dimention single-crystal X-ray analysis.
All intensity data were collected with an Enraf-Nonius CAD4 diffractometer, using graphite monochromated Cu-K_α radiation and ω/2θ scan, and corrected for LP and emperical absorption factors. All crystal structures were solved by MULTAN and refined by full matrix least-squares with lsotropic thermal vibration factors for H and anisotropic for the others.
Crystal data, (I) X=NH, R=H, ...
