 Title    Uber ein neues Oxoiridat(V) vom Sr4P t0 6-Typ: NaSr3Ir06 On a New O xoiridate(V) of the Sr4P t 0 6 Type: NaSr3I r 0 6  
 Abstract    Single crystals of NaSr3I r 0 6 have been prepared by heating mixtures of Na20 2, SrO and iridium in closed silver tubes and were investigated by X-ray techniques^ NaSr3I r 0 6 crystal­ lizes with trigonal (rhombohedral) symmetry in the space group D 3d-R 3 c , a = 9.636(2), c = 11.556(3) A , Z = 6, and is isotypic to compounds of the Sr4P t 0 6 type. The substitution of Sr2+ by N a+ in NaSr3I r 0 6 led to an ordered metal distribution and an increase of the oxida­ tion state from IrIV to Irv.

 Title    Zur Kristallchemie eines Natrium-Cadmium-Oxoiridats: Na3Cd2lr06 On the Crystal Chemistry of a Sodium Cadmium Oxoiridate: Na3C d-Jr06  
 Abstract    Single crystals of Na3Cd2Ir0 6 have been prepared by crystallization from melts in closed silver tubes. The crystal structure was investigated by X-ray techniques. Na^Cd^IrOf, crystallizes with monoclinic symmetry, space group Cih-C2/m; a = 5.663(2), b = 9.783(3), c = 5.689(2) A, ß = 109.95(2)°, Z = 2. It is isotypic to M+5A7+0 6 (M = Li, Na; A = Re, Os) and shows relations to the sodium chloride structure in spite of an ordered distribution of Na+, Cd2+ and Ir5+.
