N2  - Complexes [XLiL3], X = Cl , Br, I; L = 4-t-butylpyridine, (1)-(3) have been synthesized by recrystallization of the anhydrous lithium halide from the parent base, and characterized structurally by single-crystal X-ray structure determination. (1) and (2) are isomorphous (monoclinic, P21), a &#8776; 11.8, b &#8776; 12.1, c &#8776; 11.8 &#506;, &#946; 120&#176;, Z 2 (R 0.051, 0.040 for No 1491, 1499 'observed' reflections); (3) is orthorhombic, Pbca, a 22.119(10), b 21.108(10), c 12.845(10) &#506;, Z 8, R 0.067 for No 967. (1)- (3) are all pseudo- trigonal and contain four-coordinate XLiN3 arrays [Li-X, 2.33(1); 2.53(1); 2.76(4) &#506;; Li-N, 2.03(1)-2.11(1); 2.04(1)-2.09(2); 2.03(4)-2.07(4)&#506;]. Similar data are also recorded for X = I, L = quinoline (4)[monoclinic, P21/c, a 15.684(6), b 7.693(4), c 26.758(12) &#506;,&#946; 107.71(3)&#176;, Z 4; R 0.072, No 3096; Li-I, 2.78(2); Li-N, 2.08(2)- 2.13(2)&#506;]. While a close parallel may be drawn between the similarity of the chemistry of lithium(I) and copper(I) in respect of (1)-(3), (4) is unusual being the first XML3 derivative for a quinoline -type ligand; it is a monoquinoline solvate.
