N2  - Syntheses and single-crystal X-ray structural characterizations (at c. 295 K) are recorded for the 1 : 1 adducts of copper(I) chloride, bromide and iodide with L = 2,2&#8242;-bipyridine. The chloride is triclinic, P&#299; , a 14.069(5), b 10.520(3), c 7.872(2)&#506;, &#945; 69.00(2), &#946; 88.62(3), &#947; 70.70(2)&#176;, Z = 4 formula units; R was 0.041 for No 1805 'observed' [I > 3&#963;(I)] reflections. The bromide is monoclinic, P21/c, a 8.788(3), b 13.206(6), c 9.895(3)&#506;, &#946; 117.90(2)&#176;, Z = 4 formula units; R 0.036 for No 1007. The iodide is monoclinic, C2/c, a 17.571(3), b 8.587(7), c 16.796(3)&#506;, &#946; 120.17(2)&#176;, Z = 8 formula units; R 0.041 for No 1038. The chloride is ionic, [CuL2]+ [ ClCuCl ]-; in the cation, Cu-N are 2.005(6)-2.039(6)&#506; with interligand N-Cu-N 114.4(3)-132.4(2)&#176;, while, in the anion, Cl-Cu-Cl is 177.3(1)&#176;, with Cu-Cl 2.086(2) and 2.091(2)&#506;. The bromide (unlike its 1,10-phenanthroline counterpart, which is ionic) is a centrosymmetric dimer , as also is the iodide. In the bromide, Cu-N are 2.083(6), 2.099(5), and Cu-Br 2.428(2), 2.463(1)&#506;, Cu&#8230;Cu and Br&#8230;Br being 2.850(1) and 3.975(2)&#506; respectively. In the iodide, Cu-N are 2.070(8), 2.08(1), and Cu-I, 2.583(3)&#506; (&#215;2), and Cu&#8230;Cu and I&#8230;I are 2.610(2) and 4.420(1)&#506;.
