Binary polyazides of cadmium and mercury

Following our interest in binary element-nitrogen compounds we report here on the synthesis and comprehensive characterization (M.p., IR/Raman, elemental analysis, 14N/133Cd/199Hg NMR) of tri-and tetraazido cadmate and mercurate anions [E(N3)(2+n)]n- (E = Cd, Hg; n = 1, 2) in a series of [Ph4P]+ and [PNP]+ ([PNP]+ = bis(triphenylphosphine)-iminium) salts. The azide/chloride exchange in CH2Cl2 as well as the formation of tetrazolate salts in CH3CN solutions of the polyazido mercurates were investigated. Single crystal X-ray structures of all new compounds, and for comparison [Ph4P][Cd2(N3)5(H2O)], were determined. Moreover, the synthesis of anhydrous cadmium(II) azide and its DMSO adduct is presented for the first time. For a better understanding of structure and bonding in E(N3)2, [E(N3)3]- and [E(N3)4]2-, theoretical calculations at the M06-2X/aug-cc-pVDZ level were carried out.

Mercurous Azide, Hg2(N3)2

White polycrystalline mercurous azide, Hg2(N3) 2, is obtained by combining aqueous solutions of NaN3 and Hg2(NO3)2·2H2O (made viscuous by addition of tetramethoxysilane and heating at 65°C). The crystal structure was solved and refined from X-ray powder diffraction data (monoclinic, P21/n, a = 596.07(2) pm, b = 1259.07(4) pm, c = 357.95(1) pm, β= 103.253(2)°, Z = 2, RB = 0.0519). Solid Hg2(N3)2 contains, essentially, molecules of that composition with Hg-Hg distances of 254.4(3) pm, Hg-N distances of 218(2) pm and Hg-Hg-N angles of 178.7(6)°. Weak intermolecular interactions with Hg-N distances starting at 280(3) pm lead to a three-dimensional structure.
