Komplexe von Germanium(II)-chlorid mit 1,2-Bis(diphenylphosphino)ethan: Ein Halb-Chelat und ein Doppel-Ylid

1,2-Bis(diphenylphosphino)ethane (dppe) reacts with the germanium dichloride dioxane complex depending on the stoichiometric ratio to give a 1:2 dppe-bridges bis(germylene)complex (1) or a 1:1 complex (2) that shows equilibration of both phosphorus atoms in 31P-NMR.The crystal structure of 2 has been determined from single crystal X-ray data.The compound crystallizes with 8 units dppe-GeCl2.0.5 C6H6 in a unit cell of symmetry A 2/a-C2h6 in a monoclinic system.The dppe-GeCl2 molecules contain a novel semi-chelating type of coordination of the dppe ligand II with an exceptionally long distance Ge-P(apical)>. 2 thus represents an intermediate structure between chelate complex and phosphorus ylid.
