Reaction of [Ru{sub 2}(O{sub 2}CMe){sub 4}]Cl and K{sub 2}[Ni(CN){sub 4}] forms [Ru{sub 2}(O{sub 2}CMe){sub 4}]{sub 2}[Ni(CN){sub 4}] with the targeted layered structure possessing Ru-N{triple_bond}C-Ni linkages, albeit strained, with Ru-N{triple_bond}C and Ni-C{triple_bond}N angles in the range of 147-167{sup o}. The magnetic properties of [Ru{sub 2}(O{sub 2}CMe){sub 4}]{sub 2}[Ni(CN){sub 4}] can be fit to a zero-field splitting model with D/k{sub B} = 95 K (66 cm{sup -1}).

High-resolution synchrotron X-ray powder diffraction and Rietveld structure refinement of two (Mg{sub 0.95},Fe{sub 0.5})SiO{sub 3} perovskite samples synthesized under different oxygen fugacity conditions

Jephcoat, A.P. ; Hriljac, J.A. ; McCammon, C.A. ; ... March 1999 - American Mineralogist

This paper presents high-resolution synchrotron X-ray powder diffraction data at 290 K on two Fe-bearing, polycrystalline silicate perovskite samples with approximate compositions (Mg{sub 0.95}Fe{sub 0.05})SiO{sub 3} synthesized at 25 GPa and 1920 K in a multi-anvil press at different oxygen fugacity conditions. Rietveld structural refinements confirm that Fe{sup 2+} and Fe{sup 3+} dominantly substitute for Mg{sup 2+} in the 8-fold to 12-fold coordinated A site for both compositions. There appears to be no significant differences in the bond distances for these amounts of Fe{sup 3+} and no conclusive structural evidence to support indications from Moessbauer experiments that Fe{sup 3+} maymore »« less

High pressure synthesis, structure solution and Rietveld refinement of polycrystalline (Ba,K)VS{sub 3} from x-ray powder diffraction data

Poulsen, N.J. December 1997 - Materials Research Bulletin

The quasi-one-dimensional hexagonal perovskites BaVS{sub 3} and BaVSe{sub 3} are susceptible to doping under high pressure. At 3 GPa, 900 C, barium was replaced with potassium, and mixed chalcogenides BaV(Se,S){sub 3} were stabilized. X-ray powder diffraction revealed that the product from the high-pressure synthesis was dominated by strain. The potassium-rich samples swiftly absorbed water in humid air. Rietveld analysis and assumption of Vegard`s law indicated that selenium can replace sulfur in all ratios, whereas potassium only partially replaces barium. In this paper, the synthesis and Rietveld refinements results for the sulfides are reported.
