研究了新型四核配合物(eta(2)-dppe)PdMn(mu(3)-C=CHPh)PdMn(mu-C=CHPh)(CO)(4)CP2(5)的晶体和分子结构。 5的金属核是弯曲链Pd(2)-Mn(2)-Pd(1)-Mn(1)。键距和角度为 Mn(1)-Pd(1) 2.6025(6)、Pd(1)-Mn(2) 2.8913(5)、Mn(2)-Pd(2) 2.6463(4) 埃、Mn(1)-Pd(1)-N1n(2) 140.2(2)度， Pd(1)-Mn(2)-Pd(2) 69.6(1)度。配合物含有两个以不同方式与金属原子配位的桥联亚乙烯基配体。 mu(2)(eta(1),eta(1))-C=CHPh 和 mu(3)(eta(1),eta(1),eta(2))-C=CHPh 配体中的 C=C 键长分别为 1.347(4) 和 1.372(4) 埃。 eta(2)-dppe 配体与 Pd(2) 原子配位形成螯合环。每个 Mn(1) 和 Mn(2) 原子均与 eta(5)-C5H5 环和两个 CO 基团键合。 (c) 2006 Elsevier B.V. 保留所有权利。
The crystal and molecular structure of the novel tetranuclear complex (eta(2)-dppe)PdMn(mu(3)-C=CHPh)PdMn(mu-C=CHPh)(CO)(4)CP2 (5) has been investigated. The metal core of 5 is a bent chain Pd(2)-Mn(2)-Pd(1)-Mn(1). The bond distances and angles are Mn(1)-Pd(1) 2.6025(6), Pd(1)-Mn(2) 2.8913(5), Mn(2)-Pd(2) 2.6463(4) angstrom, Mn(1)-Pd(1)-N1n(2) 140.2(2)degrees, Pd(1)-Mn(2)-Pd(2) 69.6(1)degrees. Complex contains two bridging vinylidene ligands coordinated to metal atoms in different ways. The C=C bond lengths are 1.347(4) and 1.372(4) angstrom in the mu(2)(eta(1),eta(1))-C=CHPh and mu(3)(eta(1),eta(1),eta(2))-C=CHPh ligands, respectively. The eta(2)-dppe ligand is coordinated to the Pd(2) atom to form the chelate cycle. Each of Mn(1) and Mn(2) atoms is bonded with the eta(5)-C5H5 ring and two CO groups. (c) 2006 Elsevier B.V.
