Synthesis and Structural and Theoretical Characterization of a Nickel (0) Complex of Tribenzocyclyne (TBC) and the Preparation of a Novel Organometallic Conductor
Abstract
Transition metal complexes of planar metallomacrocycles, including ligand systems such as the porphyrins and phthalocyanines, have been studied in depth as precursors for 1-dimensional conductors. These complexes have several key features in common: the molecules are planar with an extend pi-system, the ligand atoms which complex the metal are relatively hard nitrogen donors, the ligand has a formal negative oxidation state and the complexes can be made conductors by either oxidation or reduction. The present work shows that the reaction of Ni(COD)2 with TBC in benzene affords a Ni(O) complex in which the nickel atom resides in the cavity of the twelve membered ring equally bound to all three alkynes. The synthesis, characterization and reaction chemistry of Ni(TBC) is presented below. In addition, the preparation of n-doped macrocyclic conductors based upon TBC and NI(TBC) are reported. Keywords: Nickel compounds, Nickel.
