摘要：

Ti(OEt)4 reacts at room temperature with a maximum of 1.33 mol equiv of methacrylic acid. This ratio is retained in the primary hydrolysis product Ti6O4(OEt)8(OMc)8 (OMc = OOC-C(Me) = CH2), which was characterized by an X-ray structure analysis. The monoclinic lattice parameters (space group P2(1)/c) are a = 1412.0 (3), b = 1710.1 (1), c = 1501.9 (2) pm, beta = 107.458 (7)-degrees, and V = 3479 x 10(6) pm3. Zr(OPr(n))4 reacts at room temperature with a maximum of about 2 equiv of methacrylic acid, and both [Zr(OPr(n))3(OMc)]n and [Zr(OPr(n))2(OMc)2]n were isolated. While the bismethacrylate compound is hydrolyzed to give [ZrO(OMc)2]n, the monomethacrylate only reacts with 1.33 equiv of water to yield a compound of the composition [Zr3O3(OH)(OPr(n))2(OMc)3]n.
