A Toluene Guest in a Poly(heteronuclear) Complex Host of Ferrocenyl−(CH2)2-Bridged Bis(pyrazole)

Abstract

Reactions of ferrocenyl−(CH2)n-bridged bis(pyrazoles) with nickelocene afforded inter- and intramolecular dimeric poly(heteronuclear) cyclopentadienylnickel(II) complexes from which a novel toluene-embodied guest−host system was obtained by π-interaction. The present paper has demonstrated a new class of potentially useful organometallic building blocks for supramolecular assembly and the first example of a pyrazolato ligand exhibiting a charge transfer type π-interaction.
