Reacting stoichiometric amounts of 1‐(diphenylphosphino)ferrocenecarboxylic acid and [Ti(η5‐C5HMe4)2(η2‐Me3SiC[triple‐bond]CSiMe3)] produced the title carboxylatotitanocene complex, [{μ‐1κ2O,O′:2(η5)‐C5H4CO2}{2(η5)‐C5H4P(C6H5)2}{1(η5)‐C5H(CH3)4}2FeIITiIII] or [FeTi(C9H13)2(C6H4O2)(C17H14P)]. The angle subtended by the Ti/O/O′ plane, where O and O′ are the donor atoms of the κ2‐carboxylate group, and the plane of the carboxyl‐substituted ferrocene cyclopentadienyl is 24.93 (6)°. 相似文献

A higher degree of coordination saturation is attainable through the unusual coordination mode in the title compound 1 , in which the central pyrazolate groups function both as chelating and as bridging ligands. There is some asymmetry in the bridging, and the N atoms of each μ-η2:η2-pyrazolato ligand are 0.07–0.11 Å closer to one of the two Yb centers. 相似文献
