摘要：

Contrary to common belief a single C-H center dot center dot center dot F-C contact in [(eta(5)-C5H5) Pd(C6F5)(PPh3)] is strong enough to pair two independent molecules and render them crystallographically different as suggested by its strongest H-1 - F-19 dipole - dipole coupling in a 2-D CP/MAS PILGRIM NMR experiment together with solid state 1-D F-19{H-1} and 2-D F-19 RFDR NMR spectroscopy - thereby proving the power of 2-D solid-state NMR for assessing the strength of supramolecular contacts.
