The geometries of adducts of europium tris(fod) and a series of alkyl substituted adamantanones have been determined with the use of lanthanide induced 1H shift measurements. The position of the Eu(III) cation relative to the substrate ligand appears to be strongly dependent upon steric interactions between the fod ligands and the alkyl groups in the substrate. The alkyl substitution causes distortions
使用镧系元素诱导的1 H位移测量已确定了tri(fod)alkyl和一系列烷基取代的金刚烷酮的加合物的几何形状。Eu(III)阳离子相对于底物配体的位置似乎强烈取决于fod配体和底物中烷基之间的空间相互作用。烷基取代导致原本为线性的CO-Eu阵列变形。通常,Eu(III)阳离子远离烷基取代基。
