Abstract: | The [(L-aspartate)di(2-pyridyl)aminezinc(II)]hydrate doped with traces of copper was prepared. Electron paramagnetic resonance spectra of the polycrystalline sample were recorded at room temperature by using the X-band of the EPR spectrometer. The observedg factors for the complex areg ‖=2.258 andg ⊥=2.066. TheA ‖ value is 165.10−4 cm−1. The crystal and molecular structure of the complex are also reported. The complex crystallizes in the monoclinic system; space groupP21 witha=7.2053(11),b=10.447(2),c=10.812(2) Å, β=108.489(14)° andZ=2. The structure can be described in the crystal lattice as polymeric chains. |
