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.
