Abstract

Zr33-O){[CH2C(CH3)2O]2}4 {[HO(CH3)2CCH2C(CH3)2O]}2 was prepared by a transesterification reaction between Zr(O-n-Pr)4 and 2,4-dimethylpentane-2,4-diol, DMPDH2. The product was obtained as a white crystalline solid containing discrete molecules of a μ3-O bridged trizirconium cluster with one chelating DMPD, two chelating DMPDH groups and three exobidentate DMPD groups, with one end bonded to a single Zr atom and the other bridging adjacent Zr atoms. The two chelating DMPDH groups form strong hydrogen bonds to the oxygen atoms of the chelated DMPD group. (C) 2000 Elsevier Science S.A.
