Abstract
The intermolecular interactions between X−H donors (X = C, N, O) and electron-rich π-ligands (alkynes, arenes, and cyclopentadienyl ligands) in crystalline organometallic complexes have been investigated from data retrieved from the Cambridge Structural Database. Intermolecular X−H---π interactions are weak hydrogen bonds following the common order of acidity HOH > HNH > HCH but become more effective packing determinants when "charge-assisted" by the presence of an ionic charge (X−Hδ+---πδ-).
