 Title    Dimers [A12N6]12-and Chains J j A lN ^ ] in the Crystal Structures of Ca6[Al2N6] and Ba3[Al2N4]  
 Abstract    Pale yellow transparent single crystals of Ca6[Al2Nö] (P 2\/c, No. 14, a = 693.7(3), b = 614.9(3), c = 987.1(5) pm, ß = 94.01(5)°; Z = 4) and colourless transparent single crystals of Ba.^ALN*] (Pnna, No. 52, a = 617.9(2), b = 1005.2(4), c = 1023.0(4) pm; Z = 4) were obtained from reactions of mixtures of the representative metals with nitrogen at Tmax = 1000 °C. The crystal structure of CaöfALNft] contains isolated units [ALNftJ12-built of two edge-sharing tetrahedra. Ba3[ALN4] is an isotype of S r^A bN ^. The crystal structure contains infinite chains ^ [A1N^T2] of trans edge-sharing tetrahedra.
