Synthetic procedures are described that allow access to anilinium salts containing the complex anions [Hg2Cl62-, [Hg2Cl4X2]2- (X = Br, I), [CdHgI6]2-, [CdHgI4Br2]2- and [CdHgBr4I2]2--. Isolated dimeric structures are proposed for the new complexes in the solid state, using X-ray powder patterns, Far-IR and Raman spectra. The spectral detail is greatly enhanced in measurements at low temperature (∼100 K).

Abstract Unexpectedly the reaction of SbCl3 with Na(N{SiMe3}2) in a 1:3 molar ratio forms MeSb(N{SiMe3}2)2, I, (Me = CH3) and other trimethylsilyl compounds. The colourless and liquid methylstibane derivative I is monomeric in solution and forms MeSbCl2(N{SiMe3}2)2 (II) on reaction with SO2Cl2. Both new compounds have been characterized by analyses, NMR, IR and Raman spectra. The X-ray structure determination for II shows the monoclinic space group P21/C with 4 monomeric units per cell. The structure was refined to an R-value of 0,052.

A Cu(II) complex of the amino acid L-selenomethionine of stoichiometry Cu(L-SeMet)2, has been prepared and characterized. Crystallographic data were obtained by means of X-ray powder diffractometry and showed that the compound is isostructural with the related complex of L-methionine, Cu(L-Met)2. The structural analogy is also supported by the analysis of the IR and Raman spectra of the complex, which are briefly discussed in comparison with those of free L-selenomethionine.

Reaction Solution

The heterometallic Sb(III)/Li cage complex [{Sb(P-t-Bu)3}2Li6·6THF] (1) is obtained by the low-temperature (<0°C) reaction of Sb(NMe2)3 with t-BuPHLi (1:3 equiv) in THF. Thermolysis of this reaction solution leads to the formation of the bicyclic distibane [(t-BuP)3Sb]2 (2). 31P NMR spectroscopic studies reveal that this process involves initial formation of [(t-BuP)3Sb]– and [t-Bu(H)PP-t-Bu]– anions. Complexes 1 and 2 have been characterized in the solid state by X-ray diffraction studies.Key words: antimony, lithium, cage.

Based on these molecular parameters the low temperature (10 K) IR and Raman spectra of the (n-Bu4N) salts have been assigned by normal coordinate analysis. The valence force constants are fd(ReN) = 1.70 (1), 1.75 (2) and 1.75 (3), fd(ReS) = 1.32 (1) and 1.37 (2) and fd(ReSe) = 1.20 mdyn/Å (3).

AbstractTri-n-butyltin diphenylphosphinate (n-Bu)3SnO2PPh2 has been synthesized by the reaction of (n-Bu3Sn)2O with Ph2POCl in toluene. An X-ray diffraction study of (n-Bu3)SnO2PPh2 shows that the structure is polymeric and consists of helical chains in which (n-Bu)3Sn groups are linked by O-P-O bridges. The geometry about tin is trigonal bipyramidal, with n-butyl groups in equatorial positions and an axial O-Sn-O angle of 176.2 (2)°. IR and Raman spectra of (n-Bu)3SnO2PPh2 are given and assigned. The mass spectrum is reported and discussed.

Complete far-IR and Raman data (<400 cm-1) are reported for triphenyltin azide (1) as well as for adducts Ph3SnN3·L (L = hexamethylphosphoramide (HMPA), triphenylphosphine oxide, pyridine-N-oxide, 4-picoline-N-oxide, or pyridine). The small changes in v(Sn-N3) noted on going from (1) to the adducts, as well as solid-state 119Sn nmr data, indicate that (1), like the adducts, has five-coordinate tin atoms. X-ray analysis shows that (1) crystallizes with two different chains of five-coordinate Ph3Sn units joined by 1,3-azide bridges. In one unit, the geometry around tin is similar to that found for the monomeric HMPA adduct (2), which has trans-axial HMPA and azide ligands. The other unit in (1) has nonplanar -SnC3- groups connected by less symmetric 1,3-azide bridges and thus resembles the structure of isoelectronic triphenyltin isocyanate.Key words: triphenyltin azide, O- and N-donor adducts, far-IR/Raman, crystal structures.

Tridodecylammonium 3,5-dinitro-1,2,4-1H-triazolate (TDADNT) was synthesized and characterized by NMR, IR, and Raman spectra, elemental analysis and TG/DTA. Its structure was further confirmed by the single crystal X-ray diffraction (Fig. 2), which shows that the compound crystallizes in the triclinic space group P-1 with a = 8.9507(19) Å, b = 12.702(2) Å, c = 19.068(4) Å, α = 72.440(5) o, β = 89.620(7) o, γ = 84.901(7) o, V = 2058.3(7) Å3, Z = 2. The salt is thermally stable up to 270 °C with the TG/DTA measurements.
