摘要：

[{Li(2,4,6-tBu3C6H2)}{LiP(H)(2,4,6-tBu3C6H2)}]2 is formed during the synthesis of LIP(H)(2,4,6-tBu3C6H2). The X-ray structural analysis shows the presence of four two-coordinate Li atoms, of which two exhibit a short Li-C(aryl) sigma-bond. The other two Li atoms exhibit nearly six identical Li-C(aryl) distances (Li-C 2.31 angstrom) and a short lithium to ring center distance (1.83 angstrom). The latter suggests an eta-6 coordination of the aromatic system to the lithium atom.
