Other Tetraarylgermanium Compounds

GeR4 compounds with substituted aryl groups and 1-naphthyl are listed in Table 20. Ge(CeDe)4 [23] is mentioned together with Ge(C6H5)4 in the preceding section (see vibrational spectra on p. 112). 

Further information on compounds preceded by an asterisk is given at the end of the table. Explanations, abbreviations, and units on p. XI.
