摘要

在1000℃下制备了硫化铕铟Eu5In5S13。单晶x射线衍射结果表明，该材料为pb4in2bi4s13型结构(正交，空间群Pbam， a = 20.722(2) Å， b = 25.911(3) Å， c = 3.9883(4) Å， Z = 4)，由eu中心的双头三角棱镜和in中心的四面体和八面体构成；两个金属位与Eu和In原子在八面体配位中无序排列。磁化率测量、电子顺磁共振波谱和151Eu Mössbauer波谱显示了Eu2+的磁性和Eu3+的非磁性共存。光学漫反射光谱显示1.5 eV的带隙，从电子结构计算可以看出，这是一个直接带隙。

Mixed-valent ternary sulfide Eu5In5S13

Europium indium sulfide, Eu₅In₅S₁₃, was prepared at 1000 °C. Single-crystal X-ray diffraction reveals that it adopts the Pb₄In₂Bi₄S₁₃-type structure (orthorhombic, space group Pbam, a = 20.722(2) Å, b = 25.911(3) Å, c = 3.9883(4) Å, Z = 4), built up from Eu-centred bicapped trigonal prisms and In-centred tetrahedra and octahedra; two metal sites are disordered with Eu and In atoms in octahedral coordination. Magnetic susceptibility measurements, electron paramagnetic resonance spectroscopy, and ¹⁵¹Eu Mössbauer spectroscopy indicate the coexistence of magnetic Eu²⁺ and non-magnetic Eu³⁺. The optical diffuse reflectance spectrum shows a 1.5 eV band gap, which is a direct one as indicated by electronic structure calculations.
