Vieira, N.C.; Pienkos, J. A.; McMillen, C. D.; Myers, A. R.; Clay, A. P.; Wagenknecht, P. S. A trans-bidentate bis-pyridinyl ligand with a transition metal hinge. Dalton Trans., 2017, 46, 15195-15199.
A titanocene based metalloligand, Cp*2Ti(C22-py)2, was synthesized and coordinated to either Cu(I) or Pd(II). The metalloligand binds Cu(I) between its alkynes and Pd(II) between its pyridinyl rings, acting as a trans-bidentate ligand. In order to bind Pd(II), significant structural rearrangements were necessary, which required the flexibility of the C-Ti-C hinge on the titanocene metalloligand.
