摘要： 对(C6H5COCHCOC6H5)6Eu·OCOCH3,和C5H5Na反应形成的(C6H5COCHCOC6H5)2EuC5H5进行了1H核磁共振谱的测定,结果表明此化合物的分子结构式应为(C6H5COCHCOC6H5)2Eu— ,即环戊二烯基与金属铕间以σ键相连.

Abstract: The PMR of (C6H5COCHCOC6H5)2EuC5H5 obtained from the reaction .between (C6H5COCHCOC6H5)2Eu·OCOCH5 and C5H5Na is taken. The structural formula of this compound is proved by the resultof its PMRanalysis to be (C6H5COCHCOC6H5)2Eu- , ie, there isa σ-bond between the cyclopentadienyl group and europium.
