3-Methoxymethyl-16β,17β-epiestriol-16β,17β-diyl sulfate
The title compound, C(20)H(26)O(6)S, synthesized by the reaction of 3-O-meth-oxy-methyl-16β-epiestriol and sulfonyl-diimidazole, is composed of a 3-meth-oxy-methyl group connected via two O atoms to a 16,17-O-sulfuryl-16-epiestriol group. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into [001] chains.

The complete mol-ecule of the title compound, C(6)H(12)N(2)O(5), is generated by a rotation about a twofold axis. The conformation along the bond sequence linking the two amino groups is trans-trans-(+)gauche-trans-trans. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular architecture.

The title compound, C(14)H(12)N(2)O(4), has twofold imposed crystallographic symmetry in the solid state. The asymmetric unit contains one half-mol-ecule. An intra-molecular C-H⋯O hydrogen bond is formed between the carboxyl-ate O group and one H atom of the aromatic ring such that a five-membered ring is formed. The angle between the planes of symmetry-related aromatic rings is 44.71 (19)°.

Mol-ecules of the title compound (alternative name: butane-1,4-diyl dinicotinate), C(16)H(16)N(2)O(4), lie on a inversion centre, located at the mid-point of the central C-C bond of the aliphatic chain, giving one half-mol-ecule per asymmetric unit. The butane chain adopts an all-trans conformation. The dihedral angle between the mean plane of the butane-3-carboxyl-ate group [for the non-H atom...
متن کاملPropane-1,3-diyl bis(pyridine-3-carboxylate)
The title compound, C(15)H(14)N(2)O(4), has a trans-gauche [O/C/C/C-O/C/C/C] (TG) conformation. The angle between the planes of aromatic rings is 76.4 (3)°. The crystal structure is stabilized by van der Waals inter-actions and C-H⋯O hydrogen bonds. The crystal used was a non-merohedral twin with a fractional contribution of the minor component of 0.443 (5).
