The reaction of Ge[N(SiMe3)2]2 with calix[6]arene furnishes a novel macrocyclic product having two divalent germanium atoms incorporated into a Ge2NO rhombus which contains a μ2-oxygen atom and a μ2-NH2 group. The crystal structure of the product indicates the presence of a conformationally rigid molecule where three of the six oxygen atoms of the calix[6]arene are bound to the germanium atoms while the remaining three have been converted into -OSiMe3 or unusual -OSi(H)(NH2)2 groups. Spectral (1H, 13C, and 29Si NMR) data in solution are consistent with the solid-state structure and indicate the germanium calix[6]arene retains its structure in solution.
