一种新的多晶型的CeNiSb 3已从锡熔剂生长，其特征在于通过单晶X-射线衍射。β-CeNiSb 3以正交晶系空间群Pbcm（No.57）结晶，Z = 8。晶胞参数为a = 12.9170（2）A、B = 6.1210（5）A、c = 12.0930（6）A和V = 956.13（9）A 3。它的层状结构包含类似于CeNiSb 3的第一种形式的结构基序，并且由插入近正方形无限大2 [Sb]网和扭曲的无限大2 [NiSb 2]八面体的阴离子层之间的Ce原子组成。我们报告的合成，磁化强度，电阻率和比热的新形式的CeNiSb 3和比较两种多晶型的结构和物理性能。
A new polymorph of CeNiSb3 has been grown from a Sn flux and characterized by single-crystal X-ray diffraction. beta-CeNiSb3 crystallizes in the orthorhombic space group Pbcm (No. 57) with Z = 8. The unit cell parameters are a = 12.9170(2) A, b = 6.1210(5) A, c = 12.0930(6) A, and V = 956.13(9) A3. Its layered structure contains structural motifs similar to that of the first form of CeNiSb3 and consists of Ce atoms inserted between anionic layers of nearly square infinity2[Sb] nets and distorted infinity2[NiSb2] octahedra. We report the synthesis, magnetization, electrical resistivity, and specific heat of the new form of CeNiSb3 and compare the structures and physical properties of both polymorphs.
