 Title    Zur Kristallstruktur der Cyanoelpasolithe [N(CH3)4]2CsCo(CN)6 und [H3NCH3]2NaFe(CN)6 Concerning the Crystal Structures of the Cyano-Elpasolites [N(CH3 )4]2CsCo(CN) 6 and [H3NCH3]2NaFe(CN) 6  
 Abstract    Single crystals of the cyano com plexes [N (C H 3)4]2C sC o(C N)6 and [H3NCH 3]2N aFe(C N)6 were prepared and their structures determined by X-ray methods. The cobalt compound is monoclinic, a -885.5(1), b = 892.6(2), c = 1259.9(5) pm, ß = 90.29(4)°, space group 12Im, Z = 2; R l = 0.048 for 861 independent reflections. The resulting average distances in the nearly undistorted octahedra are C o -C = 189.8, C -N = 114.1, C s -N = 325.6 pm. The iron compound exhibits a cubic elpasolite type structure, a = 1105.2(1) pm, space group Fm 3m , Z = 4; R l = 0.040 for 127 independent reflections; F e -C = 193.4(6), N a -N = 247.7(8) pm. The orientation of the librating tetramethyl-ammonium group within the cages of the cobalt compound and the disorder of the monomethyl-ammonium cation around the special site (1/4, 1/4, 1/4) of the iron complex are discussed.
