✦ Synopsis
The introduction of three methyl groups into the ips0 positions analysis) in the solid state. Treatment of 5 with Ir(PPh&(CO)Cl of the cyclohexane ring in cis,cis-l,3,5-tris[(diphenylphos-gives 6 where the two PPh3 groups are replaced by two (diphanyl)methyl]cyclohexane (tdppmcy) (1) leads to the new phenylphosphany1)methyl groups of the ligand 5. In addition, tripodal phosphane ligand cis,cis-1,3,5-tris[(diphenylphos-an intramolecular C-H metalation takes place resulting in the phanyl)methyl]-l,3,5-trimethylcyclohexane (tdppmtmcy) (5). oxidative addition of a ring methylene C-H bond to the metal. The dynamic behavior is studied by variable-temperature NMR spectroscopy and compared with the structure (X-ray The X-ray structure of 6 is determined.

## Abstract The preparation of a family of dinuclear monocyclopentadienyl imidoniobium and ‐tantalum complexes was achieved by two different synthetic routes. The diimido complexes [{M(Cp′)Cl~2~}~2~(μ‐1,__i__‐NC~6~H~4~N)] [Cp′ = η^5^‐C~5~H~4~SiMe~3~, M = Nb, __i__ = 4 (1); Cp′ = η^5^‐C~5~H~4~SiMe~3
