A comparative study of the infrared spectra and magnetic susceptibilities of Cu(3-C7H9N)2Cl2 and Cu(4-C7H9N)2Cl2

Synthesis, structural, spectral (FT-IR, FT-Ra, and UV–Vis), thermal, and density functional studies on p-methylaniline complexes of Mn(II), Co(II), and Ni(II) bromides

“…Transition metal complexes have applications on several areas including biochemistry, analytical chemistry, magnetism, nano-technology, and medicine [1][2][3][4][5][6][7][8][9][10][11][12][13].…”

“…to 566/634/607 cm -1 . The metal-sensitivities of these modes arise from their couplings with the M-N vibrations.The metal-ligand bands that appear in the far IR region (below 600 cm -1 ) are characteristics of the local structure around metal ions[7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][46][47][48]. The υ(M-N) stretching vibrations appear at 217 cm -1 (medium IR) / 220 cm -1 (weak Raman) for the Mn complex, at 247 cm -1 (strong IR) for the Co complex, and at 273 cm -1 (medium IR) / 155 cm -1 (medium Raman) for the Ni complex.…”
