The electrical conductivity of coordinated polychelates derived from bissemicarbazone and bisthiosemicarbazone of 5. 5′-methylene-bis-salicylaldehyde with Cu(II), Co(II), Ni(II), and Mn(II) metal ions was measured at various temperatures. The results for polychelates of both ligands showed that the conductivity varied as Cu(Il) > Ni(II) > Co(II) > Mn(II) polychelate, and that the activation energy, E, increased from Cu(II) through Ni(II) and Mn(II) to Co(II) polychelates. Hall effect and Seebeck effect studies of Cu(II) polychelates revealed that they are found as p-type semiconductors and that the mechanism of transport is of the hopping type.
