The syntheses and Mossbauer spectra of four sulphur-chelated compounds of tin(11) are reported. A single-crystal X-ray structure determination of Sn(dedtc)2 has established that the molecule possesses a strongly distorted trigonal bipyramidal configuration with a sterically active lone pair of electrons occupying an equatorial coordination position. While the Mossbauer quadrupole splitting for tin(11) compounds, in general, is consistent with a sterically active pair of electrons, its magnitude appears to be more sensitive to the nature of the ligand rather than the tin stereochemistry.

The structure of K2Pt(CN)4Cl2 has been determined and refined from X-ray powder data. All compounds crystallize monoclinicly (P21/c; Z = 2), and K2Pt(CN)4X2 with X = Cl, Br, I are isostructural.

AbstractThis study presents the first crystal-structure determination of natural MgCO3·5H2O, mineral lansfordite, in comparison with previous structural works performed on synthetic analogues. A new prototype single-crystal X-ray diffractometer allowed us to measure an extremely small crystal (i.e. 0.020 mm × 0.010 mm × 0.005 mm) and refine anisotropically all non-hydrogen atoms in the structure and provide a robust hydrogen-bond arrangement. Our new data confirm that natural lansfordite can be stable for several months at room temperature, in contrast with previous works, which reported that such a mineral could be stable only below 10°C.

The isolation and single-crystal X-ray structure determination of the title compound, [(phen)2Pb(NCS)(O2NO)] is described; crystals are triclinic, P1, a 15.554(7), b 9-670(4), c 8.429(3) α 72.53(3), β 81.90(3), γ 72.88(3)� Z = 2, yielding R 0.052 for 3405 independent 'observed' reflections. The lead atom is seven-coordinate [Pb-N 2.49(1)-2.60(1) (phen), 2.89(1) (NCS); Pb-O 2.75(1), 2.89(1) �] with a large vacancy in the coordination sphere, possibly indicative of a stereochemically active lone pair.

Abstract The title compounds have been synthesized via oxidation of the elemental pnicogenes (M = As, Bi) with the hyperoxides AO2 (A = K, Rb, Cs) and their crystal structures were determined on the basis of single crystal X-ray data. In K3AsO4 (orthorhombic, Cccm, a = 1060:1(1), b = 1135:2(1), c = 1694:0(2) pm, Z = 16) and Cs3AsO4(orthorhombic, Pnma, a = 1254:3(2), b = 902:9(2), c = 658:5(3) pm, Z = 4) isolated tetrahedra [AsO4]3- with distances As-O between 167.0 and 170.5 pm are present, which are arranged in a nearly cubic close packing. The structure of K3BiO4 (triclinic, P1̄, a = 643:18(6), b = 657:27(6), c = 762:41(7) pm, α = 101:724(2)°, β = 96:472(2)°, γ = 105:465(2)°, Z = 2) contains centrosymmetric dimers [O3BiO2BiO3]6-, in which the Bi(V) atoms are surrounded by five O atoms in a distorted trigonal bipyramidal geometry with distances Bi-O in the range of 199.5 to 233.1 pm.

The synthesis and room-temperature single-crystal X-ray structure determination of the title compound are recorded. Crystals are monoclinic, P 21/c, a 14.43(2), b 18.39(1), c 23.64(3) Ǻ, β 123.16(7)°, Z = 4, isostructural with the recently described Fe3Ru5 analogue; R was 0.048 for 6892 'observed' data [I > 3σ(I)]. The cluster is one of the few containing separated carbide ligands within a polyhedral metal skeleton, consisting of an Ru5C square pyramid and an Ru6C octahedron sharing a triangular face, with two PPh2 groups bridging opposite Ru-Ru vectors in each polyhedron.
