The crystal and molecular structures of deacetylthiocolchicine hydrochloride dihydrate and thiocolchicine hexahydrate were determined by X-ray diffraction. The replacement of oxygen by sulfur on the C ring methoxy group causes greater puckering of the troponoid ring. The conformation of one A ring m

Abstract
The synthesis and X‐ray analysis of a sulfur dioxide analog of the diuretic agent triamterene, namely 4,7‐diamino‐1‐methyl‐6‐phenylpyrazino[2,3‐c][1,2,6]thiadiazine 2,2‐dioxide (2b), is reported. The compound is devoid of the diuretic properties found in other related pyrazino[2,3‐c][1,2,6]thiadiazines. magnified image

## X-ray emission spectra of S Kb, S and O Ka for sulfur dioxide were calculated by the discrete variational Xa L 2, 3 (DV-Xa) method. The absolute energies of the peaks in the theoretical spectra agree with the experimental values within an error of 3% . The relative energies and intensities of p
SAS, 3-p-aminoethyl-5-hydroxybenzo(b)thiophene, the sulfur analog of serotonin, has proved refractory to synthesis. The various steps in its preparation have been refined, and its preparation in overall yield of about 20 percent in an eight-step sequence from commercially available m-hydroxyacetophe
A solvate complex of (-)-1-menthoxygermatrane with chloroform (1) was obtained by reaction of (-)-menthoxytriethylstannane with 1 -bromogermatrane in chloroform. The crystal and molecular structure of 1 was established by X-ray analysis.
