title: Two germatranes with bulky substituents.
abstract: In 1-adamantyl-2,8,9-trioxa-5-aza-1-germabicyclo[3.3.3]undecane or 1-adamantylgermatrane, [Ge(C(10)H(15))(C(6)H(12)NO(3))], (I), and (2,8,9-trioxa-5-aza-1-germabicyclo[3.3.3]undecan-1-yl)methyl N-cyclohexylcarbamate or [(germatran-1-yl)methyl] N-cyclohexylcarbamate, [Ge(C(6)H(12)NO(3))(C(8)H(14)NO(2))], (II), the Ge atoms are characterized by trigonal-bypiramidal configurations. The Ge...N distances [2.266 (3) and 2.206 (3) A 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.
