N2  - The 1:2 adducts of the copper(I) halides (CuX ; X = Cl, Br, I) with the aliphatic/aromatic bidentate nitrogen bases 2-aminomethylpyridine, H2NCH2.C5H4N, and 2-hydrazinopyridine, H2N.NH.C5H4N, L, have been synthesized by recrystallization of stoichiometric copper(I) halide/base solutions from acetonitrile . In all cases, ionic complexes [CuL2]+ X- are obtained, copper being four-coordinated by a pair of bidentate ligands, and with widely varying distortions from ideal 2 symmetry. Cu-N (aromatic) in the 2-aminomethylpyridine adducts range from 1.979(8) to 2.037(5)&#506;; while Cu-N(H2) are 2.102(9)-2.172(10)&#506;, N( Ar )-Cu-N( Ar ) angles [130.7(2)-143.2(4)&#176;] are larger than N(H2)-Cu-N(H2)[114.8(2)-116.3(4)&#176;]. Comparable values for the 2-hydrazinopyridine complexes are 1.95(1)-2.036(5), 2.085(4)-2.214(7)&#506;; 124.1(2)-140.8(4), 94.5(3)-128.0(3)&#176;. In no case does the halide anion coordinate to the copper, displacing the aliphatic nitrogen donor group; rather it is stabilized in the crystal lattice by strong NH2&#8230;X hydrogen bonding.
