摘要：

Cd(II) and Cu(II) complexes of an acyclic pentadentate Schiff base were prepared by template condensation of two equivalents of 2-acetylpyridine with one equivalent of bis(3-aminopropyl)-amine in methanol. The resulting complexes [CdL(NO(3))]ClO(4) (1) and [CuL](ClO(4))(2)center dot CH(3)CN (2) were characterized by X-ray crystallography, elemental analysis, IR and mass spectrometry in both cases and by NMR in the case of 1. The X-ray crystallographic structure determination of these complexes revealed six-coordinate distorted octahedral geometry for 1, with the sixth coordination by nitrate and five-coordinate for 2 with trigonal-bipyramidal Cu(II).
