Abstract:
Reaction of Me 2 SbBr or Et 2 SbBr with AgN 3 in ether affords Me 2 SbN 3 and Et : SbN 3 . respectively. Me 2 SbN 3 can also be obtained from Me 2 SbNMe 2 and HN 3 in ether. Me 2 BiN 3 from Me 2 BiN(SiMe 3 ) 3 and HN 3 in ether. Me 2 SbN 3 and Et 2 SbN 3 dissolve as monomers in benzene; 1 H, 13 C, ia N and 15 N NMR spectra of the solutions are reported. IR and Raman spectra of solid Me 2 SbN 3 and Et 2 SbN, as well as the mass spectrum of Me 2 SbN 3 are assigned. The crystal structures of Me 2 SbN 3 and Me 2 BiN 3 were determined by X-ray diffraction data collected at -67 °C (888 and 439 reflexions, R = 0.024 and 0.076. respectively). Both compounds are isotypic, space group Pnma. Z = 4. Crystal data: Me 2 SbN 3 , a = 843.6. b = 919.3, c = 744.1 pm: Me 2 BiN 3 , a - 870.8. b = 911.3, c = 738.4 pm. In the crystals, the metal atoms are linked via the aN atoms of the azido groups to form endless zig-zag chains. Whereas the Bi -N distances are equal. Sb-N bonds alternate with two different lengths (232 and 243 pm). Including the lone pair of electrons, the metal coordination can be described as distorted trigonal bipyramidal, with nitrogen atoms occupying the apical positions. With new X-ray diffraction data collected at -100 °C, the crystal structure of Me 3 PbN 3 was refined (1692 reflexions, R = 0.036). Crystal data: a = 656.3, c = 1377 pm. space group P3 2 21, Z = 3. It consists of endless metal-nitrogen chains of helical symmetry. the Pb atoms having trigonal bipyramidal coordination.
