The aggregation of metalloorganic nematogenic molecules of 4,4’-bis(hexyloxy)azobenzene-palladium complex (AZPAC) is analyzed by using recent measurements of volume polarization of AZPAC. The dipolar electric moment of the AZPAC molecule has been measured. The average aggregation number and also the energy required for this aggregation have been estimated. The superparaelectric behavior of AZPAC has been thus explained.
