eng	Different hydrolytic stabilities of some C,N-chelated germanium alkoxides	C,N-intramolecularly coordinated germanium(IV) methoxides Ar3GeOMe (1) and (Ar ')(2)Ge(OMe)(2) (2) [where Ar = [2-(Me2NCH2)C6H4](-), Ar ' = [2-(DipN = CH)C6H4](-), Dip = 2,6-(i-Pr)(2)C6H3] were prepared by the reaction of the lithium precursors ArLi and Ar ' Li with Ge(OMe)(4) in appropriate molar ratio. While the diorganogermanium(IV) compound 2 is air-stable specie, triorganogermanium(IV) compound is surprisingly smoothly hydrolyzed by air-moisture to corresponding triorganogermanol Ar3GeOH (3). Studied compounds were characterized by the help of multinuclear NMR spectroscopy and in the case of 2 and 3 using single-crystal X-ray diffraction analysis.
