A new compound, Fe1.52+Pb5.52+In103+S222-, was found in the Fe-Pb-In-S system. The crystals had a shiny metallic gray luster and were obtained in a barlike shape. The melting and recrystallizing points are 1098 and 1090 K, respectively. The crystal structure determined by X-ray diffraction is P2/m, a = 14.558(1) angstrom, b = 3.8556(3) angstrom, c = 15.558(1) angstrom, beta = 96.876(1)degrees, V = 867.0(1) angstrom(3), Z = 1, D-c = 5.893 g/cm(3), and R1 = 3.78%, which is an isostructure with Sn5.5In11S22. In the structure, lead atoms exist at three crystallographically independent sites, and one of them, Pb1, is occupied by a quarter of indium atoms. All of the Fe ions are randomly distributed at six indium sites. This compound is a semiconductor with a band gap, E-a = 0.95 eV. The dominant magnetic interaction is antiferromagnetic, but magnetic orderings are not observed down to 2 K.
