Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The structures of three newly synthesized phosphonate‐substituted polyoxotitanates are reported. The Ti/O core of [Ti₄O(OEt)₁₂(PhenylPO₃)] (<bold>1</bold>) is the building block for two larger phosphonate‐substituted nanoclusters, [Ti₂₅O₂₆(OEt)₃₆(PhenylPO₃)₆] (<bold>2</bold>) and [Ti₂₆O₂₆(OEt)₃₉(PhenylPO₃)₆]Br (<bold>3</bold>). All compounds exhibit a not previously recognized triply bridging binding mode of the phosphonate anchor with short connecting TiO bonds, the average of which is 2.010(7) Å. Comparison with previously reported work suggests that the binding mode of the phosphonate anchor is strongly dependent on the structure of the underlying substrate.</p> </abstract>
