Crystal structure of benzoyldeoxyaconine hydrobromide.

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.

Crystal and molecular structure of 4-amino-4-carboxyl thiapyran hydrobromide

4-Amino-4-carboxylthiapyran hydrobromide crystallizes in the monoctinic space group P21/m, with a = 9 . 7 2 A , b = 6 . 6 0 A a n t i c = 7 . 1 0 A , /3=94.8 ~ and Z = 2. The structure was solved by the heavy atom method with 786 observed reflections and refined to an R of 0.076. There is an interesting weak interaction which the hetero sulfur atom of the thiapyran ring makes with a symmetry re...

SYNTHESIS AND CRYSTAL STRUCTURE OF [PPh ] [WOS (CUNCS) ]

The reaction of [PPhJ, NOS,] with CuCl and KSCN (1 :3:3) in acetone produces the yell-ow crystals of [PPh,], [WOS,(CuNCS),]. The crystals are triclinic, space group P1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), Y= 65.194(4)'. The crystal structure was determined by single crystal Xray diffraction methods (Mo-K ?) and refined by least-squares calculations ...
