Abstract
Single crystals of NaLuCl4 (orthorhombic, Pbcn (Nr. 60), Z = 4, a = 61 8.6(1) pm, b = 1592.2(2) pm, c = 657.0(1) pm) were grown for the first time from the binary components using the Bridgman technique. The cry stal structure may be derived from a hexagonally closest packing of Cl - spheres with one half of all octahedral sites occupied by the cation s Na+ and Lu3+, respectively. The close relation of the structure to t hat of NaErCl4 (alpha-NiWO4) is discussed. NaScCl4 was found to be iso typic to NaLuCl4.
