Journal ArticleDOI
X-Ray crystal and molecular structure of 3β-acetoxy-6,7-epidithio-19-norlanosta-5,7,9,11-tetraene, the stable dithiete tautomer of a dithio-o-quinone
Robin B. Boar,David W. Hawkins,James F. McGhie,Satish C. Misra,Derek H. R. Barton,Mark F. C. Ladd,David C. Povey +6 more
TL;DR: In this article, the preparation and structure determination of the title compound, a representative of a novel structural class, is described, and the structural properties of the compound are discussed. But the authors do not describe the structure determination process.
Journal ArticleDOI
The characterisation of 1,1-diphenylstannacyclopentane and 1,1,6,6-tetraphenyl-1,6-distannacyclodecane. An X-ray diffraction study of the distannacyclodecane
Alwyn G. Davies,Man-Wing Tse,John D. Kennedy,William McFarlane,Geoffrey S. Pyne,Mark F. C. Ladd,David C. Povey +6 more
TL;DR: The first oligomeric stannacycloalkane, 1,1,6,6-tetraphenyl-1, 6-distannacy-clodecane (A) has been isolated, together with the monomer 1, 1-diphenylstannacyCLopentane (B), from the reaction between butane-1.4-diyl- [graphic omitted] dimagnesium dibromide and diphenyltin dichloride as mentioned in this paper.
Journal ArticleDOI
The crystal structures of propane-1,3-diammonium tetrachlorochromate(II), a sheet ferromagnet, and bis(dimethylammonium) tetrachlorochromate(II) an antiferromagnetic compound containing isolated [Cr3Cl12]6– units
Mushtaq A. Babar,Mark F. C. Ladd,Leslie F. Larkworthy,David C. Povey,Kevin J. Proctor,Lesley J. Summers +5 more
TL;DR: X-ray crystallographic studies have shown that the ferromagnetic complex propane-1,3-diammonium tetrachlorochromate(II) contains layers of chlorine-bridged [CrCl4]2] units, but antiferromagnetic bis(dimethyl-ammonium) tetrACHlorochrome(II), in which the metal atoms are arranged linearly as discussed by the authors.
Journal ArticleDOI
Molecular and crystal structure of hexamethylenetetramine oxide
TL;DR: The crystal and molecular structure of hexamethylenetetramine oxide, (CH2)6N4O, has been determined by X-ray analysis and the structure refined by full-matrix anisotropic least squares to R 0.053 for 228 diffractometer data as mentioned in this paper.
Journal ArticleDOI
Formation and X-ray crystal structure of 1,1,6,6-tetraphenyl-1,6-distannacyclodecane
Alwyn G. Davies,Man-Wing Tse,John D. Kennedy,William McFarlane,Geoffrey S. Pyne,Mark F. C. Ladd,David C. Povey +6 more
TL;DR: In this paper, the 119Sn and 13C n.m.r spectra of 1,1-diphenyl-stannacyclopentane and 1, 1,6,6-tetraphenyl 1, 6-distannacy clodecane have been rationalised, and the structure of the latter compound has been shown by single-crystal X-ray diffraction to be of "boat-chair-boat" type, similar to that of cyclodecANE.
