Abstract: Fourteen new triphenylgermanium derivatives of alkynyl or alkenyl phosphonic acid were synthesized by the reaction of corresponding triphenylgermanium chloride with alkynyl or alkenyl phosphates. All compounds were characterized by elemental analysis, IR, 1H NMRand MS. The results showed that bis(triphenylgermanium) alkynyl or alkenyl phosphonates are both four- and five-coordinated germanium and triphenylgermanium alkynyl or alkenyl phosphonates are five-coordinated germanium.
