Die Kristall‐ und Molekülstruktur von {article}{empty}{document}P^ + CH₂ BH₃{document}

The Crystal and Molecular Structure of {article}{empty}{document}P^ + CH₂ BH₃{document} The zwitterionic molecule (CH3)3{article}{empty}{document}P^ + CH₂ BH₃{document} crystallizes orthorhombicly, space group Pna21. While the CH3 groups in (CH3)3PCH2 are bent away from the ylidic function, this strain is relieved in the adduct towards tetrahedral angles. The PCH2 bond distance is elongated on BH3‐addition from a double bond value of 164 to a single bond distance of 175.6 pm.
