SYNTHESIS AND MOLECULAR-STRUCTURE OF CIS-[PD(C6F5)2(C6H5CH2NME2)], AN INTRAMOLECULAR COORDINATION COMPOUND CONTAINING AN UNUSUAL ETA-1-ARENE LIGAND

Benzyldimethylamine as C,N‐chelate ligand in which, in addition, the phenyl ring is η1‐coordinated; this is the surprising feature of the structure of the title complex (right: section without C6F5 ligands). The PdC7 distance (2.335(7) Å) is greater than a PdC σ‐bond, but smaller than that in an η2‐arene‐Pd complex. Despite η1‐coordination, the phenyl ring is planar, and all CC bond lengths and CCC angles are equal. Possibly the complex has model character for intermediates in orthometalations.
