Single-crystal X-ray structure determinations have been carried out at 295 K on the compounds [Cul (phen)]*0.5MeOH (1) (phen = 1,l O-phenanthroline), [Cul(dmphen)] (2),[C uBr(dmphen)] (3), and [CuCl(dmphen)] (4) (dmphen = 2,9-dimethyl-l,1 O-phenanthroline). Crystals of (1) are monoclinic, P 2 , h a = 10.659(3), b = 23.585(9), c = 10.487(3) A, p = 91.34(2)", Z = 8; for No = 2 457 independent 'observed' diffractometer reflections, R = 0.034. Crystals of (2) are monoclinic, C2/c, a = 19.025(6), b = 8.489(3), c = 17.376(5) A, p = 108.27(2)", Z = 8; No = 1 582, R = 0.035. Crystals of (3) are isomorphous with (2), a = 18.497(6), ...

Crystals of (3) are isomorphous with (2), a = 18.497(6), b = 8.398(2), c = 17.419(5) A, p = 110.14(2)"; No = 1 786, R = 0.040.

In (1 )-(3), the species is a di-p-halogeno-bridged dimer with four-co-ordinate copper atoms. For (I), Cu-l are 2.589(1)-2.632(1) A with CU-N 2.078(6)-2.103(6); Cu Cu is 2.609(2) and I I, 4.454(2) A. In (2), Cu-l are 2.673(1), 2.563(1), Cu-N, 2.094(6), 2.092(5); Cu Cu is 3.024(2) and I 0 . - I, 4.276(1) A. In (3), Cu-Brare 2.400(1), 2.559(1), Cu-N, 2.083(5), 2.085(4) A; Cu Cu is 3.097(1) and Br Br, 3.876(1) A. Complex (4) is mononuclear with the copper atom pseudo-trigonally planar co-ordinated by the bidentate aromatic ligand [Cu-N 2.060(6) and 2.057(5) A] and the halide [Cu-CI, 2.1 26(2) A]. The role of the ligand and halide substituents on the complexity of the complex is examined.
