Abstract
The crystal structure of the title compound was determined from single crystal X-ray data. The compound crystallises in the orthorhombic space group Pnma. In contrast to the solution where fluctuating P-Te bonds have been established by NMR analyses the crystals contain isolated molecules with fixed P-Te bonds (bond length: 235.4 pm). The four-membered phosphorus nitrogen ring exhibits significant deviations from planarity. The P-N bond lengths were found to be 168.3 and 175.0 pm, respectivelyKeywords
