Abstract Tin(IV) complexes of diacidic azo and hydrazono compounds were synthesized by the reaction of these ligands with SnCl2acac2 and SnCl2 · 2H2O , respectively. The complexes were further characterized by Mössbauer spectroscopy. For bis[4-(2′-hydroxyphenylazo)-3-methyl-l-phenyl-pyrazol-5-onato(2-)]tin(IV) force field calculations have been performed and the crystal structure was determined by X-ray analysis.

Group 6

Three complexes, [M(CO)5Tz], have been synthesised by the photochemical reaction of 3,5-dimethyl-1,2,4-triazole (Tz) with [M(CO)6] (M = Cr, Mo and W). The crystal structure of [Cr(CO)5Tz] has been characterised by X-ray analysis, and the 4 H-tautomer of the triazole ligand is observed in this complex in the solid state.

AbstractThe crystal structure of strontian potassicrichterite (Mg4.871Fe0.1263+ Mn0.052)Σ5.049(Na1.425Ca0.348Sr0.297)σ2.07K0.873Si8.048O22(OH)2.15 – an unusual amphibole containing up to 3.7 wt.% SrO from the Murun alkaline massif, Eastern Siberia has been refined from X-ray powder diffraction data in monoclinic space group C2/m, with a = 10.0325(1) Å, b = 17.977(1) Å, c = 5.2698(1) Å, and β = 104.70(1)°. According to Mössbauer spectroscopy, nearly all iron occurs as Fe3+ in octahedral coordination. Rietveld refinement shows the Fe3+ to be ordered onto the M(2) site. Sr is completely ordered onto M(4).
