| Summary: | 碩士 === 國立師範大學 === 化學學系 === 81 === The following new organogermanium compounds were successfully
ynthesized from germanium dioxide and some organic acid: L-
lysine-germanate (1a-c), L-argin- ine-germanate (2a-c), Bis(
citrato-O,O',O'')germanium (IV) (3), Ammonium bis(citramalato-O,
O',O'')germanium (IV) (4),Ammonium bis(L-malato-O,O',O'')
germanium(IV) (5), Poly-[diaqua-bis( tartarato-O, O')germanium
(IV) (6), Dipyridine-bis(salicylato-O,O')germanium(IV)(7),
Diaqua-bis(gallato-O,O')germanium(IV)(8), Bis(iminodi- acetato-
O,O')germanium(IV)dihydrate (9), Hydroxo[ N,N- bis
(2-hydroxyethyl)glycinato-O,O',O''] germanium(IV) (10). Product
1 and 2 are germanium oligomers. The X- ray structure of
compound 3a and 4 have been per- formed. 3a is triclinic, 4
is monoclinic, both 3a and 4 have a slightly distorted
octahedral structure. The structure of compound 5 is similar
to that of com- pound 3a and 4. Products 6-9 have a
octahedral structure. 10 is a trigonal bipyramidal structure.
All the structures were identified by IR,NMR, elemental
analysis or mass.
