Neutron and X-Ray Structure Determination of Laurionite-Type Pb{O(H,D)}X, withX= Cl, Br, and I, Hydrogen Bonds to Lead(II) Ions as a Hydrogen-Bond Acceptor

Autor: Heinz Dieter Lutz, Konrad Beckenkamp, Thomas Kellersohn, Stefan Peter, H. Möller

Publikováno v: Journal of Solid State Chemistry. 124:155-161

The crystal structures of Pb(OH)Br, Pb(OH)Cl, Pb(OD)Br, and Pb(OD)I have been refined by single-crystal X-ray and neutron diffraction, and neutron powder Rietveld methods, respectively. The laurionite-type structures (Pnma, Z = 4; wR{sub 2} = 4.85%,

Experimental electron density of the ozonide ion (O3-) in potassium ozonide, KO3

Autor: Nikolaus Korber, Thomas Kellersohn, Martin Jansen

Publikováno v: Journal of the American Chemical Society. 115:11254-11258

The deformation electron density in potassium ozonide has been determined by multipole refinement with the Hirshfeld formalism using single-crystal X-ray data collected at 170 K. No electron excess is observed in the oxygen-oxygen bond regions of the

ChemInform Abstract: Synthesis and Crystal Structure of the First '1,2-Diphospha(4) radialene'

Autor: Walter Brieden, Thomas Kellersohn

Publikováno v: ChemInform. 24

1,2-Diphosphetane 4, the first “1,2-diphospha[4]radialene”, has been prepared in 83% yield by the reductive coupling reaction of 2,3-bis(chloroisopropylphosphanyl)butadiene 3a with lithium in THF. The X-ray crystal structure of 4 was determined,
