Abstract The crystal structures of LiN 3* H 2 O (P63/mcm (No. 193), Z = 6; 924.01(13); 560.06(7) pm); NH 4 N 3 (Pmna (No. 53), Z =4; a=889.78(18), b=380,67(8), c=867.35(17) pm); Ca(N 3 ) 2 (Fddd (No. 70), Z = 8; a=595.4(2), b=1103.6(5), c=1133.1(6) pm), Sr(N 3 ) 2 (Fddd (No. 70), Z =8; a= 612.02(9), b = 1154.60(18), c = 1182.62(15) pm); Ba(N 3 ) 2 (P2 1 /m (No. 11), Z = 2; a = 544.8(1), b = 439.9(1), c = 961.3(2) pm, β = 99.64(3)°) and TlN 3 (I4/mcm (No. 140), Z = 2; 618.96(9); 732.71(15) pm) have been either determined for the first time or redetermined by X-ray diffraction on single crystals. The afore mentioned compounds, AN 3 (A = Na, K, Rb, Cs), M(N 3 ) 2 · 2.5 H 2 O (M = Mg, Zn) and the cyanamides Li 2 CN 2 , CdCN 2 and CuCN 2 were investigated by Raman and IR spectroscopy (KBr technique). Structural features and spectroscopic data of azides and cyanamides from this work and from literature are listed and compared.
