Abstract
Two polyfunctional lithium amides, (2-C5H4N)C(CH3){CH2N(Li)SiMe2R}22 R = Me (3), tBu (4), have been synthesized and structurally characterized by X-ray crystallography. They were found to have dimeric structures containing ladder-type Li-N arrangements in which the form of aggregation and thus folding of the ladder appears to be influenced by the steric demand of the N-bonded silyl groups. Substitution of the lithium ions by thallium(I) was achieved in two steps, yielding the mixed metal amide (2-C5H4N)C(CH3){CH2N(Li)SiMe3)CH2N(Tl)SiMe3}]2 (5) and the thallium(I) diamide (2-C5H4N)C(CH3) {CH2N(Tl)-SiMe3}22 (6). X-ray diffraction studies of both compounds revealed a dimeric ring structure through Li-N links for the former, while the latter is monomeric and only weakly aggregated in the crystal structure through a short, unsupported thallium(I)-thailium(I) contact of 3.500(2) Ã .
