A monoclinic modification of propane-1,3-diyl bis(pyridine-3-carboxylate)
In the title compound, C(15)H(14)N(2)O(4), (I), the mol-ecule lies on a twofold rotation axis which passes through the central C atom of the aliphatic chain, giving one half-mol-ecule per asymmetric unit. The structure is a monoclinic polymorph of the triclinic structure previously reported [Brito, Vallejos, Bolte & López-Rodríguez (2010). Acta Cryst. E66, o792], (II). The most obvious differen...

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).

Mol-ecules of the title compound, C(17)H(18)N(2)O(4), lie on a twofold rotation axis that passes through the central methyl-ene C atom. The mol-ecules adopt a 'V' shape and the trimethyl-ene unit assumes a gauche-gauche conformation. The amino N atom shows a nonplanar coordination. Adjacent mol-ecules are connected by N-H⋯O hydrogen bonds into chains running along [001]. Furthermore, N-H⋯N hydr...
متن کاملPropane-1,3-diyl bis(pyridine-4-carboxylate)
The title compound. C(15)H(14)N(2)O(4), (I), has a gauche-gauche (O/C/C/C-O/C/C/C or GG) conformation and is a positional isomer of propane-1,3-diyl bis-(pyridine-3-carboxyl-ate), (II). The mol-ecule of (I) lies on a twofold rotation axis, which passes through the central C atom of the aliphatic chain, giving one half-mol-ecule per asymmetric unit. There is excellent agreement of the geometric ...
متن کاملPropane-2,2-diyl di-p-phenylene dibenzoate
The V-shaped propeller-like mol-ecule of the title compound, C(29)H(24)O(4), does not exhibit crystallographic twofold symmetry as the two benzene rings are twisted asymmetrically with respect to both the central propyl plane and the benzo-yloxy groups [4.6 (2), 43.6 (2)° and 45.07 (8), 69.50 (8)°]. In the crystal structure, centrosymmetrically related mol-ecules form a dimer through C-H⋯π inte...
