Magnetic, spectral, thermal, and electrical properties of polychelates

Coordination polymers of copper, nickel, cobalt, manganese, and zinc with poly(Schiff base) derived from 5,5'‐methylene‐bis‐salicylaldehyde and 4,4'‐diaminodiphenyl methane have been prepared. Elemental analysis, magnetic, spectral, and thermal properties, and electrical conductivities of the chelates have been studied and probable structures assigned to the chelates. The analytical data propose a [ML] n formula for the chelates. The site of coordination of the ligand with metal ions has been elucidated by comparing the IR spectra of the ligand and polychelates. All the polychelates are stable and insoluble in common solvents.
