Seven new complexes are reported with nitrobenzene as the ligand, viz. [M(C6H5NO2)6]2+[SbCl6]2− with M is Mg(II), Ca(II), Mn(II), Fe(II), Co(II), Ni(II), and Zn(II). No shift in the NO stretching frequencies has been observed. The NO2 out of plane bending vibration shifts to higher frequencies dependent on the metal ions. Investigation of ligand field spectra indicates the presence of octahedral species M(nitrobenzene)62+ in the solid compounds. Values for Dq and B for the Co and Ni compounds are reported. |
