چکیده

Although the title mol-ecule, C(20)H(16)N(2)O(10), does not possess mol-ecular inversion symmetry, it lies on a crystallographic inversion centre which imposes disorder on the central cyclo-hexene ring. In addition, the cyclo-hexene ring has non-symmetry-related disorder over two sites, with the ratio of the major and minor components being 0.54:0.46. The overall effect is to produce four disorder components for the atoms of the cyclo-hexene ring. The side chain is perfectly ordered and the dihedral angle between the atoms of the carbonate group (O=CO(2)-) and the benzene ring is 72.99 (6)°.

trans-Cyclo­hexane-1,4-diyl bis­(4-nitro­phen­yl) dicarbonate

In the title crystal structure, C(20)H(18)N(2)O(10), there are two independent mol-ecules, both of which lie on crystallographic inversion centres. In one mol-ecule the 4-nitro-phenyl dicarbonate groups are substituted in equatorial (A(eq)) positions of the chair-form cyclo-hexane ring while in the other mol-ecule the substitution is axial (B(ax)). The dihedral angles between the atoms of the s...

The title structure, C(22)H(24)N(2)O(10), contains two independent centrosymmetric mol-ecules. The only significant difference between the mol-ecules is the dihedral angle between the unique carbonate group (-O-CO(2)-) and the benzene ring, the values being 77.35 (8) and 66.42 (8)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

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...
