Dimethyltin chromate and basic dimethyltin and diphenyltin carbonates have been isolated for the first time. Structural features of these compounds, as well as of the previously known basic dimethyltin chromate, have been investigated by examining their infrared, Raman, and Mössbauer spectra. Infrared, Raman, and Mössbauer spectra of [Me2Sn(NCS)]2O have also been examined, and by comparing its spectroscopic data with those for (Me2Sn)2OCrO4, (Me2Sn)2OCO3, and (Ph2Sn)2O(CO3), possible structures have been suggested for the latter compounds. From the combined infrared and Mössbauer data, a structure is also proposed for Me2SnCrO4. All compounds are indicated to have polymeric structures with bridging CrO42− or CO32−.

The preparations are reported of an extended series of compounds of the type ML2X4 where M is Mn, Fe, Co, or Ni; X is Cl or Br; and L is analytically identical with dithioacetylacetone. ��� Electronic, infrared, and Mossbauer spectra together with the temperature dependence of the magnetism (80-300�K) of these compounds establish-contrary to previous suggestions in the literature-that they should be properly formulated as tetrahalometallate salts of the 3,5- dimethyl-1,2-dithiolium cation. Simple salts of this cation (such as the iodide) have also been isolated. ��� During the course of this work salts (I- and [CoCl4]2-) of the hitherto unknown 3,5-dimethyl-1,2-diselenolium ion were synthesized and characterized for the first time.

Mossbauer Spectra

119Sn Mössbauer and vibrational spectra for a number of SnF62− and SnCl62− complexes have been obtained. One fundamental for the SnF62− ion has been reassigned. Strong evidence for anion–cation interaction for (ClO2)2SnF6 is obtained both from the vibrational spectra and from the Mössbauer spectra where a non-zero quadrupole splitting is found.

Abstract The crystal structures of LiN3*H2O (P63/mcm (No. 193), Z = 6; 924.01(13); 560.06(7) pm); NH4N3 (Pmna (No. 53), Z =4; a=889.78(18), b=380,67(8), c=867.35(17) pm); Ca(N3)2 (Fddd (No. 70), Z = 8; a=595.4(2), b=1103.6(5), c=1133.1(6) pm), Sr(N3)2 (Fddd (No. 70), Z =8; a= 612.02(9), b = 1154.60(18), c = 1182.62(15) pm); Ba(N3)2 (P21/m (No. 11), Z = 2; a = 544.8(1), b = 439.9(1), c = 961.3(2) pm, β = 99.64(3)°) and TlN3 (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, AN3 (A = Na, K, Rb, Cs), M(N3)2 · 2.5 H2O (M = Mg, Zn) and the cyanamides Li2CN2, CdCN2 and CuCN2 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.

The reaction of the ditertiary arsines and phosphines fnfars, fnfos, and fnAsP, (L–L), with Fe(CO)5 at 150° is a superior route to the complexes (L–L)Fe2(CO)6. Two are reported for the first time (L–L = f6fars, f8fars). The complexes react with monodentate and certain potentially bidentate ligands on u.v. irradiation to afford the monosubstituted derivatives L(L–L)Fe2(CO)5 and (L–L)'(L–L)Fe2(CO)5. Spectroscopic studies, in particular magnetically perturbed Mössbauer spectra, indicate that the site of substitution is trans to the FeA—FeB bond and cis to the two group V atoms (on FeA). Disubstitution seems to result in further displacement of CO from either FeA or FeB.

Frozen Solutions

125Te Mössbauer data for frozen solutions of tellurium in HSO3F and in oleum are reported together with data for solid samples which may have contained the Te42+, Tenn+, and Te62+ cations. The data demonstrate that the quadrupole splitting reflects the sequential oxidation of the tellurium through the steps Te → Te42+ → Tenn+ → Te(II) → Te(IV) → TeO2. The quadrupole splittings for samples identified as containing Te42+ are consistent with a unit quadrupole splitting of 12 mm s−1 for 125Te.
