Abstract

Reaction of the bulky pyridyl based ligand 6-Me(2-Pyr)(Me₃Si)₂CH with ⁿBuM (M = Na, K) in the presence of the N donors pmdta (N,N′,N′,N″,N″ pentamethyldiethylenetriamine) and tmeda (N,N,N′,N′ tetramethylethylenediamine) resulted in the formation and crystallisation of the heavy alkali metal complexes, [{6-Me(2-Pyr)}(Me₃Si)₂CNa(pmdta)], 1, and [{6-Me(2-Pyr)}(Me₃Si)₂CK]_∞, 2. Single crystal X-ray diffraction studies show the sodium complex, 1, to be monomeric with a six coordinate metal centre, while the unsolvated potassium complex, 2, is polymeric, involving repeating η³ 1-aza-allyl and allylic interactions of the pyridyl moiety with the potassium cation.
