摘要

In order to deepen Our understanding of the versatile behaviour of adenine (Hade) as ligand, we have synthesized four novel ternary copper(H) complexes having two deazaadenine ligands, namely 4-azabenzimidazole (H4abim) or 7-azaindole (H7azain) as N1,N6-dideazaadenine or N1,N6,N7-trideazaadenine, respectively. The related Compounds were studied by thermal, spectral and single crystal X-ray diffraction methods. In [Cu(NBzIDA)(H4abim)](n) (1) the recognition between H4abim and the (N-benzyliminodiacetate)-copper(II) chelate only displays the formation of the Cu-N7(purine-like) bond. in contrast to Hade behaviour in [Cu(NBzIDA-like)(Hade)(H2O)]center dot H2O (Cu-N3(Hade) bond reinforced by N9-H center dot center dot center dot O(IDA-like) interaction). In [Cu(EIDA)(H7azain)(H2O)] (2, EIDA=N-ethyliminodiacetate ligand), [Cu(NBzIDA)(H7azain)(H2O)] (3) and [Cu(mu(2)-SO4)(H7azain)(2)(H2O)2](n) (4), H7azain binds Cu(II) centre by the Cu-N3(purine-like) bond. reinforced by a N9-H center dot center dot center dot O(IDA-like or sulfate) intra-molecular interligand interaction.
