摘要

制备了一种新型金属间化合物Ca7Ni4Sn13的晶体。精细结构在P4/m空间群中求解，Z=1，晶格常数a=11200A和c=4.594（1）a，R=2.8%和Rw=2.4%。这种新的结构类型由Sn-Ni网络组成，该网络形成平行于c轴的通道，通道中填充有钙原子。温度相关的磁性和导电性研究表明，Ca7Ni4Sn13是泡利顺磁性的，具有简单的金属行为。

Synthesis, structure and properties of a new intermetallic compound, Ca7Ni4Sn13

Crystals of a new intermetallic compound, Ca₇Ni₄Sn₁₃, have been prepared. The refined structure was solved in the P4/m space group, Z = 1 with lattice constants $a = 11.200(1) A ̊$ and $c = 4.594(1) A ̊$ , R = 2.8% and R_w = 2.4%. This new structure type consists of an Sn-Ni network forming channels parallel to the c axis which are filled with calcium atoms. Temperature-dependent magnetic and conductivity studies show Ca₇Ni₄Sn₁₃ to be Pauli paramagnetic with simple metallic behavior.
