摘要：

Polynuclear cyclohexasiloxanolates M(6)L(2) and M(n)M'(6-n)L(2) (M, M' = Ni, Mn, Fe; L = [-SiPh(O)O-](6)) were studied as precursors of supported catalysts. Synchrotron EXAFS data (Novosibirsk VEPP-3 storage ring, 2.5 GeV, 120 mA, Si[111] monochromator) revealed three closest coordination spheres: M-O (2.0-2.2 Angstrom), M ... M (2.72-2.98 Angstrom) and M ... Si (3.31-3.40 Angstrom). Interatomic distances for M = Ni or Mn agree with the known X-ray structures of 'tubular' M(6)(mu(2)-O)(12) cores.
