The authors describe the synthesis of the silanol ligands, HOSi(t-Bu){sub 3{minus}n}[(CH{sub 2})NME{sub 3}]{sub n} (3, n = 2; 4, n = 1). These ligands react with Ln[N(SiMe{sub 3}){sub 2}]{sub 3} yielding the complexes Ln(OSi(t-Bu){sub 3{minus}n}[(CH{sub 2}){sub 3}NMe{sub 2}]{sub n}){sub 3} (5, Ln = Y, n = 2; 6, Ln = y, n = 1; 7, Ln = Ce, n = 1). X-ray diffraction of single crystals of 6 was used for structural characterization. 6 reacts with Ln[N(SiMe{sub 3}){sub 2}]{sub 3} to give Ln[OSi-(t-Bu){sub 2}(CH{sub 2}){sub 3}NMe{sub 2}]{sub 3}[OSi(t-Bu){sub 2}(CH{sub 2}){sub 3}NMe{sub 2}]{sub 3}[OSi(t-Bu){sub 2}(CH{sub 2}){sub 3}NMe{sub 2}H] (8, Ln = Y; 9, Ln = Yb). X-ray diffraction of single crystals of 9 was used for structural characterization.
