| Abstract | ||
| A series of new complexes of the type [M2LCl4] and [M2L2Cl4] where M=Mn(II), Co(II), Ni(II) and Cu(II), L={1,3-Bis(2-amino-5-nitropyridine)isophthylidene} have been prepared. Adduct complexes of the type [M2L(PPh3)2Cl2]Cl2 were M= Co(II) and Ni(II) were also prepared in 1:2 (complex: PPh3) molar ratio. The complexes were characterized by molar conductance, magnetic moment, and FT-IR, UV-visible spectral studies and metal content analysis. Conductivity data showed that the complexes were non-electrolytes and the PPh3 adducts were 1:2 electrolytes. Magnetic moments and electronic spectra indicate that the complexes have either tetrahedral or octahedral geometry while the complex Ni2LCl4 has square planer configuration. | ||
