A \u3cem\u3etrans\u3c/em\u3e-bidentate \u3cem\u3ebis\u3c/em\u3e-pyridinyl ligand with a transition metal hinge

Abstract

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
