Abstract
The reaction of (Me2N)(3)SiCH2CH2NMe2 with 2-amino-4-nitrophenol (mola r ratio 1:2) in acetonitrile yields the zwitterionic spirocyclic lambd a(5)Si-silicate nio)ethyl]bis[4-nitrobenzene-2-aminato-1-olato(2-) (7) . Compound 7 was characterized by H-1, C-13,and Si-29 solution-state a nd Si-29 solid-state NMR spectroscopy, in addition to single-crystal X -ray diffraction. The SiO2N2C framework of 7 is characterized by five ''normal'' covalent bonds.
