The silyl-substituted titanocene complex, (eta5-C5Me4SiMe2Ph)2Ti, coordinates dinitrogen upon cooling to -35 degrees C to yield an unprecedented example of a mono(dinitrogen) complex of a substituted bis(cyclopentadienyl) titanium compound, (eta5-C5Me4SiMe2Ph)2Ti(N2). Analogous monocarbonyl derivatives, (eta5-C5Me4R)2Ti(CO) (R = SiMe3, SiMe2Ph, CHMe2), have been prepared by mixing the dicarbonyl compounds with the corresponding sandwiches. Both (eta5-C5Me4SiMe2Ph)2Ti(N2) and (eta5-C5Me4SiMe2Ph)2Ti(CO) have been characterized by X-ray diffraction, and mixed N2-CO titanocene complexes have also been observed by in situ IR spectroscopy.
硅基取代的二茂钛配合物(η⁵-C₅Me₄SiMe₂Ph)₂Ti在冷却至-35℃时与二氮配位，生成了取代双(环戊二烯基)钛化合物的单(二氮)配合物(η⁵-C₅Me₄SiMe₂Ph)₂Ti(N₂)的一个前所未有的例子。通过将二羰基化合物与相应的夹心化合物混合，制备了类似的单羰基衍生物(η⁵-C₅Me₄R)₂Ti(CO)（R = SiMe₃、SiMe₂Ph、CHMe₂）。(η⁵-C₅Me₄SiMe₂Ph)₂Ti(N₂)和(η⁵-C₅Me₄SiMe₂Ph)₂Ti(CO)均已通过X射线衍射表征，并且通过原位红外光谱也观察到了混合的N₂-CO二茂钛配合物。
