“…Goel and co-workers were the first to do a systematic study in this direction and synthesised a number of compounds of the type (Ph 3 SbX) 2 O (X ¼ Cl, Br, ClO 4 , NO 3 , NCS, N 3 and NCO), as well as of the type (R 3 Sb 2 ) 2 OX (X ¼ C 2 O 4 , SO 4 and SeO 4 ) 4,5 and determined their structure by a crystallographic study as well as by vibrational spectral data 12 . The IR data were interpreted in favour of a non-ionic, pentacoordinated structure, possibly involving bridging anionic groups and planar triphenylantimony moieties, but when X is replaced by a highly electronegative group, such as perchlorate or nitrate, the antimony is no longer pentavalent but ions are present instead 13 .…”

Several new m-oxybis[tri(a-naphthyl)antimony(V)] derivatives of the general formula (R 3 SbL) 2 O (where R ¼ a-C 10 H 7 ; L ¼ N 3 , CN, SCN; ON¼CPh(OH)CHPh, ON¼C(CH 2 ) 4 CH 2 , OOCC 6 -H 4 NH 2 -p, OOCC 6 H 5 , OOCC 6 H 4 Cl-p, and NCO(C 6 H 4 )CO have been prepared by the interaction of (R 3 SbCl) 2 O with the appropriate metal salts of the ligand. (R 3 SbN 3 ) 2 O could also be obtained by the interaction of R 3 SbCl 2 with NaN 3 (1:2 molar ratio) in ether=water solvent mixture. The newly synthesised complexes have been characterised by elemental analyses, IR spectra, molecular weights and conductance measurements. A trigonal-bipyramidal geometry around the antimony atom with a Sb-O-Sb linkage is tentatively suggested.

“…The structural characterization of antimony azide species was so far only possible when organic ligands were present, except for the ternary antimony(V) species (SbCl 4 N 3 ) 2 [6]. The structure of the molecules {[(PN t Bu) 2 [9] and [(C 6 H 5 ) 3 SbN 3 ] 2 O [10] could be solved by X-ray diffraction. The weak crystallization tendency of Sb(N 3 ) 3 prompted us to find a better crystallizing antimony azide species having a minor azide content.…”

SbCl(N 3 ) 2 was synthesized by the reaction of two equivalents of sodium azide with SbCl 3 in CH 2 Cl 2 . The structure of the compound was determined by X-ray structure determination. SbCl(N 3 ) 2 crystallizes in the monoclinic space group C2/c with a = 11.694(4), b = 7.751(4) and c = 12.241(5) A Ê , b = 100.45(1)°, with 8 formula units per unit cell. The SbCl(N 3 ) 2 molecules show interactions to form chains. The frequencies obtained by Raman and infrared spectroscopy were assigned to the normal modes of the SbCl(N 3 ) 2 molecules in comparison with computational results.Synthese, Charakterisierung, Kristallstruktur und hybrid-DFT-Berechnung von Antimon(III)-chlorid-diazid, SbCl(N 3 ) 2 Inhaltsu È bersicht.

The Lewis acid base complexes AsCl(N 3 ) 2 ·pyridine and SbCl 2 N 3 ·2 pyridine were prepared. The products formed were characterised by Raman, IR and NMR spectroscopy. Density functional theory (B3LYP) was applied to calculate structural and vibrational data. Vibrational assignments of the normal modes for the isolated compounds were made on the basis of their vibrational spectra in comparison with com-
