Abstract

Bis(cyclopropylethynyl)zirconocene shows a bisected conformation in the crystal: the magnitude of the stabilizing conjugation of the Cp2Zr Lewis acid centre with the cyclopropyl substituent across the connecting C[triple bond, length as m-dash]C triple bond is assessed by DFT calculations and a comparison with a series of cationic organic and organometallic reference systems.
