temperature. The crystal structures of these novel phases were determined from single-crystal X-ray diffraction data and represent a new structure type in tin chemistry. They crystallize in the space group Pbcn (No. 60, Z = 4) with a = 12.772(1), b = 10.804(1), and c = 12.777(1) A, V = 1763.1(2) A(3) for Na(5)Zn(2.28)Sn(9.72(2)) (I) and a = 12.958(1), b = 10.984(1), and c = 12.960(1) A, V = 1844.5(2)
两种同源和同构化合物 Na(5)M(2+x)Sn(10-x) (M = Zn, Hg) 是通过元素在高温下的直接反应获得的。这些新相的晶体结构由单晶 X 射线衍射数据确定,代表了锡化学中的一种新结构类型。它们在空间群 Pbcn (No. 60, Z = 4) 中结晶,a = 12.772(1), b = 10.804(1), and c = 12.777(1) A, V = 1763.1(2) A(3)对于 Na(5)Zn(2.28)Sn(9.72(2)) (I) 和 a = 12.958(1), b = 10.984(1), and c = 12.960(1) A, V = 1844.5(2) A (3) 对于 Na(5)Hg(2.39)Sn(9.61(1)) (II)。该结构由一个阴离子 3D 开放框架组成,该框架由四面体协调的 Sn 和 M 原子与互连的 NaNa(4)} 四面体的阳离子
