In 1-adamantyl-2,8,9-trioxa-5-aza-1-germabicyclo[3.3.3] undecane or 1-adamantylgermatrane, [Ge(C10H15)(C6H12NO3)], (I), and (2,8,9-trioxa-5-aza-1-germabicyclo[3.3.3]undecan-1yl) methyl N-cyclohexylcarbamate or [(germatran-1-yl) methyl]-cyclohexylcarbamate, [Ge(C6H12NO3)(C8H14NO2)], (II), the Ge atoms are characterized by trigonal-bypiramidal configurations. The Ge center dot center dot center dot N distances [2.266 (3) and 2.206 (3) angstrom in (I) and ( II), respectively] are among the longest observed in germatranes. The significant distortion of the apical N-Ge-C angle in (II) is caused by crystal packing effects.
