Abstract

cis-Inositol monohydrate, C6H12O6.H2O, crystallizes in the monoclinicspace group P2(1)/n[a 9.900(8), b 9.296(8), c 17.795(15) Angstrom, beta 90.5(1)degrees, Z 8]. The normalized structure factors E(h) have anatypical statistical distribution, and attempts to solve the structure by direct methods (triplet relationships) were unsuccessful. The structure was ultimately solved by Patterson and Fourier methods, and wasrefined by full-matrix least squares [R(w) = 0.047 for 1665 independent reflections greater than or equal to 2 sigma(I-min)]. The cis-inositol molecules have approximately trigonal symmetry, as expected. The difficulties encountered during the structure analysis are explained bythe presence of two nearly identical molecules of high symmetry in the asymmetric unit. The independent molecules are related by translational pseudosymmetry, and their orientations are such that all the C-C and C-O bonds in the structure are approximately parallel to a small number of directions.
