Crystal Structure and Absolute Configuration of the Hydrobromide Salt of ( - ) - 2 - exo -
The configuration of one of the four isomers of 2-aminonorbornane-2-carboxylic acid (C8H1302N) has been determined to be (lR,2R,4S) by X-ray crystallography, utilizing anomalous scattering. The hydrobromide salt of this isomer, (-)-2-exo-aminonorbornane-2-carboxylic acid, cryst$lizes in space group P212121 with four molecules per unit cell of dimensions a = 6.986, b = 22.669, and c = 6.150 A.

متن کاملAbsolute structure and absolute configuration.
Fundamental notions concerning absolute structure and absolute configuration, and their determination from single-crystal diffraction measurements, are presented and reviewed. A glossary of terms with definitions useful in this field is provided. For absolute structure and its determination, the separate but interacting influences of the structure and the inversion-distinguishing power of an X-...
متن کاملPREPARATION AND MOLECULAR STRUCTURE OF 2-BENZYLAMINOPYRIDINE COPPER(1) COMPLEX
2-Benzylaminopyridine (HBAP) reacts with NaH in THF and generates the sodium salt (NaBAP). Further reaction of [Cu(TMEDA) ] [CuCl ] with one equivalent of this ligand in THF leads to the formation of a dimeric Cu(1) complex, [Cu (BAP)] . H 0. The molecular structure has been determined by using a single-crystal X-ray diffraction method. The yellow compound crystallizes in the monoclinic s...
متن کاملThe Crystal Structure and Absolute Configuration of 2 ' - Deoxycytidine Hydrochloride
2'-Deoxycytidine hydrochloride (C9H14N3Q4Cl) was crystallized from water as monoclinic needles, space group P21, with a=6-561, b= 17·659, c=5·125 A, P= 108·08° and two molecules per cell. The crystal structure has been determined by a three-dimensional X-ray diffraction analysis. A complete hemisphere of data (positive and negative values of both hand k) was collected with a General Electric XR...
متن کاملReporting and evaluating absolute-structure and absolute-configuration determinations
Detailed practical and numerical information is provided for undertaking and evaluating absolute-structure and absolute-con®guration determinations. The interpretation of numerical values of x, the Flack [Acta Cryst. (1983), A39, 876± 881] parameter, and its standard uncertainty u are explained in terms of the inversion-distinguishing power. Moreover, the conditions to obtain reliable values of...
