Rerefinement of (μ-1,7,11,17-tetraoxa-2,6,12,16-tetraazacycloeicosane-κ4N1,N17:N7,N11)bis[dichlorozinc(II)]. [Dataset] (2002)

This rerefinement of the title compound, [Zn2Cl4(C12H28­N4O4)], based on the original intensity data, differs from the original only in the exchange of the NH and O moieties of the oxa­aza-macrocycle, resulting in a dramatic improvement in the R fact...

VAN MEERVELT, L., KONG THOO LIN, P. and BROWN, D.M. 1995. 6-(3,5-Di-O-acetyl-β-D-2-deoxyribofuranosyl)-3,4-dihydro-8H-pyrimido[4,5-c][1,2]oxazin-7(6H)-one. [Dataset] Acta crystallographica section C: crystal structure communications [online], 51(7), pages 1347-1350. Available from:

The title compound, C15H19N3O7 (P), crystallizes with two molecules in the asymmetric unit which differ in sugar and oxazino ring puckering; both occur as the imino tautomer and form P;P wobble base pairs. The supporting information for the published... Read More about 6-(3,5-Di-O-acetyl-β-D-2-deoxyribofuranosyl)-3,4-dihydro-8H-pyrimido[4,5-c][1,2]oxazin-7(6H)-one. [Dataset].
