A New Type of Hybrid Magnetic Semiconductor Based upon Polymeric Iodoplumbate and Metal−Organic Complexes as Templates

A new type of one-dimensional organic−inorganic hybrid [M(en)3]Pb2I6 [M = Mn (1), Fe (2), Zn (3), Ni (4); en = ethylenediamine] has been obtained and structurally characterized by X-ray crystallography, which opens a new approach to construct hybrid magnetic semiconductors. The results of optical absorption spectra and theoretical calculations for compounds 1−3 reveal a quantum confinement effect, and the variable-temperature magnetic susceptibility measurements for 1, 2, and 4 indicate ferromagnetic, antiferromagnetic, and paramagnetic behavior, respectively.
