Synthesis of pentacoordinated germanium compounds containing a phosphonyl group

Abstract

Abstract The title compounds were prepared by the reaction of germanium sesquioxides with diethyl N,N‐bis(2‐hydroxyethyl)aminomethylphosphonate in good yields (72–94%). The X‐ray analyses showed that the geometry about the germanium atom was a distorted trigonal bipyramid. © John Wiley & Sons, Inc.
