N2 - Reaction of the bulky pyridyl based ligand 6-Me(2-Pyr)(Me3Si)(2)CH with (BuM)-Bu-n (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)(2)CNa(pmdta)], 1, and [{6-Me(2-Pyr)}(Me3Si)(2)CK](infinity), 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 eta(3) 1-aza-allyl and allylic interactions of the pyridyl moiety with the potassium cation.
