N2  - A number of diamagnetic complexes of copper(I) and 4,6,4',6'-tetramethyl-2,2'-bipyridine (tmb) have been prepared and some physical properties measured. The complexes of formula Cu(tmb)2X where X = NO3, ClO4, Br, and I behave as 1 : 1 electrolytes in nitrobenzene and nitromethane, while the complex Cu(tmb)2Cl,H2O apparently undergoes partial dissociation in these solvents. All are expected to have a tetrahedral arrangement of the four donor nitrogen atoms about the copper atom. The mono complexes CuXtmb, where X = Cl, Br, and I, appear to be dimeric in the solid state with halogen bridging, but in solution the chloro and bromo complexes rearrange to varying degrees depending on the solvent, forming the salt-type compounds [Cu(tmb)2][CuX2]. CuItmb is insoluble in all common solvents.
