Methyl 6-deoxy-6-iodo-α-d-galactoside
In the crystal of the title compound, C(7)H(13)IO(5), the molecules are linked by O-H⋯O hydrogen bonds, which build linkages around one screw axis of the cell. These C(5) and C(6) packing motifs expand to R(2) (2)(10) and C(2) (2)(11) motifs and are similar to those found for closely related compounds. The galactoside ring has a (1)C(4) chair conformation.

The structure of the title compound, C(7)H(13)N(3)O(5), was solved using data from a multiple fragment crystal. The galactoside ring adopts a (4)C(1) chair conformation. In the crystal, the molecules are linked by strong O-H⋯O hydrogen bonds, which build linkages around the screw axis of the cell in a similar way to the iodo analogue. These C-5 and C-6 packing motifs expand to R(2) (2)(10), C(2...
متن کاملMethyl 6-deoxy-6-iodo-2,3-O-isopropylidene-α-d-mannopyranoside
In the title compound, C10H17IO5, the six-membered tetra-hydro-pyran ring and the five-membered 1,3-dioxolane ring adopt sofa and envelope conformations, respectively. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into layers nearly parallel to the bc plane.
متن کامل6-Iodo-2-methyl-1,3-benzothiazole
The title compound, C(8)H(6)INS, is essentially planar, the largest deviation from the mean plane being for the I atom [0.075 (3) Å]. The crystal structure is mainly stabilized by inter-molecular C-I⋯N halogen bonds, forming zigzag supra-molecular chains in [10]. Relatively short off-set π-π contacts [centroid-centroid distance = 3.758 (2) Å] between the thia-zole rings of inversion-related mol...
متن کاملAn orthorhombic polymorph of 6-deoxy-6-iodo-1,2:3,4-di-O-isopropylidene-α-d-galactopyranoside
The title compound, C(12)H(19)IO(5), is the ortho-rhom-bic polymorph of a previously reported monoclinic form [Krajewski et al. (1987 ▶). Bull. Pol. Acad. Sci. Chem.35, 91-102]. The dihedral angles between the six-membered ring and the two five-membered rings are 67.66 (14) and 71.79 (13)°, whereas the dihedral angle between the five-membered rings is 74.41 (12)°, indicating that all three ring...
