Abstract Crystalline adducts of compositions (CF 3) 4 Ge· nRNH 2 (R= H: n= 2, 3; R= CH 3: n= 1, 2 with dissociation vapour pressures at 22 C of 70 (R= H) and 75 mbar (R= CH 3) have been isolated. From their Raman spectra both NH 3 adducts are judged to have a cis- configurated octahedral coordination at the germanium atom. Reaction of (CF 3) 3 Gel with NH 3 yielded the digermazane [(CF 3) 3 Ge] 2 NH whereas the cyclic trimers [(CF 3) 2 ...
