 Title    Sr3[Al2N 4l: Ein Nitridoaluminat mit gewellten Tetraederketten * [AlN4/23 ] Sr3[Al2N 4]: A Nitridoaluminate with Corrugated Tetrahedral Chains j,[AlN4/23_]  
 Abstract    Sr3[Al2N 4] (Pnna, Nr. 52; a = 590.1(3), b = 1000.5(5), c = 958.0(4) pm; Z = 4) was prepared from the elements (m olar ratio Sr: A1 = 3:1; reaction with N 2, 1 atm, 24 h; Tmax = 1 1 0 0 °C). The crystal structure contains corrugated chains ifA lN ^ 3'] which consist of distorted A1N4 tetrahedra sharing com mon edges (A l-N : 188.5(7)-195.8(7) pm; N -A l-N : 95.0(3)-126.0(5)°). The nitrogen atom s form a distorted ccp arrangement. 3/4 of the octahedral holes are occupied by Sr atoms; 1 /4 o f the tetrahedral holes are occupied by A1 atoms. Sr3[Al2N4] can be described in terms o f the Zintl concept (isosteric relation of [AIN,]3-to SiS-,).
