The molecular structures of several tetraphosphetanes are reported and discussed. The torsion-angle of the four-membered rings varies from 22,5 to 45,7 depending on the size und electronegativity of the exocyclic ligands.deinfo:eu-repo/semantics/openAccessAminophosphine , Kristallstruktur , NMR-Spektroskopie540article
