Rare earth (RE) complexes of 3-benzoylpropanoate (bp), [RE(bp)₃(H₂O)_n] (RE = La, n = 2; RE = Y, Ce, Pr, Nd, Yb, n = 1) and 3-phenylpropanoate (pp), [RE(pp)₃] (RE = Y, La, Ce, Nd, Yb), have been prepared by metathesis reactions between the corresponding rare earth chloride and the appropriate sodium carboxylate. Analysis by single-crystal X-ray diffraction finds that both RE bp and pp complexes favour formation of carboxylate-bridged 1-D coordination polymers in the solid state. Here, the former favours heteroleptic 9 or 10-coordinate complexes (splitting between Ce and La) with the carbonyl remaining uncoordinated but participating as a hydrogen bond acceptor with water in the coordination sphere. Lack of bp carbonyl coordination leaves this group available for surface interactions during corrosion inhibition and complex solubilization. The latter pp derivatives form eight-coordinate complexes for Y and Yb and are the first examples of homoleptic RE pp complexes to be reported.

3-苯甲酰基丙酸酯（bp），[RE（bp）₃（H ₂ O）_n ]的稀土（RE）络合物（RE = La，n  = 2; RE = Y，Ce，Pr，Nd，Yb，n  = 1）和3-苯基丙酸酯（pp），[RE（pp）₃通过相应的稀土氯化物和适当的羧酸钠之间的复分解反应制备了[RE]（RE = Y，La，Ce，Nd，Yb）。通过单晶X射线衍射分析发现，RE bp和pp络合物均有助于形成固态的羧酸酯桥连的1-D配位聚合物。在此，前者偏爱杂配9或10配位配合物（Ce和La之间的拆分），羰基保持未配位，但作为氢键受体与水一起参与配位球。缺乏bp羰基配位使得该基团可用于腐蚀抑制和复杂增溶过程中的表面相互作用。后者的pp衍生物形成Y和Yb的八坐标络合物，并且是报道的均纯RE pp络合物的第一个实例。
