摘要：

[Li(C6H7)(C6H16N2)], M(r) = 202.27, orthorhombic, Pbca, a = 11.238 (2), b = 16.014 (3), c = 14.522 (3) angstrom, V = 2613.5 (8) angstrom 3, Z = 8, D(x) = 1.028 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 0.549 cm-1, F(000) = 896, T congruent-to 173 K, R = 0.042 [1845 data, I > 2-sigma(I)]. The structure consists of discrete (eta-5-C5H4CH3) Li.tmen units (tmen = N,N,N,'N'-tetramethylethylenediamine). The Li atom is coordinated by the methylcyclopentadienyl ring and the two N atoms of the chelating tmen ligand. The average Li-C distance is 2.258 angstrom; the Li-N distances are 2.130 (3) and 2.124 (3) angstrom.
