![عکس صفحه اول مقاله: Synthesis, spectral, and structural investigation of [ML(NO3)2]: M = Co, Ni, Cu; L = N-(2-pyridylethyl)pyridine-2-methylketimine Synthesis, spectral, and structural investigation of [ML(NO3)2]: M = Co, Ni, Cu; L = N-(2-pyridylethyl)pyridine-2-methylketimine](/preview/png/1338475.png)
Synthesis and structural characterization of distorted pentagonal bipyramidal Co(II), pseudo-octahedral Ni(II) and Cu(II) complexes of the type [ML(NO3)2], {L = N-(2-pyridylethyl)pyridine-2-methylketimine} are reported. Characterization includes elemental analysis, spectral, magnetism, and X-ray crystallographic studies. In case of cobalt (1) both the nitrates coordinate in bidentate fashion resulting overall distorted pentagonal bipyramidal geometry. In nickel (2) and copper (3) complexes, bivalent metal ion is coordinated by the three nitrogen atoms of the tridentate L with two pyridine-N occupying trans positions and amongst the two nitrates one coordinates in a bidentate fashion while other adopts a monodentate fashion. All the complexes exhibit d–d transitions in the visible region. Complex 1 is high-spin in nature and the X-band EPR spectra of 1, and 3 at room temperature and 77 K are reported.
