1,2-Bis(phenylphosphoryl)ethane
The geometric parameters of the mol-ecule of the title compound, C(14)H(16)O(2)P(2), are in the usual ranges. It is a meso compound with the two chiral P atoms having opposite configurations. The P-CH(2)-CH(2)-P chain adopts a trans conformation [torsion angle -178.59 (17)°]. The P=O bonds are almost coplanar with the adjacent phenyl ring [torsion angles = 3.8 (3) and 0.3 (3)°]. Whereas one of ...

The title compound, C(14)H(8)N(6)O(12), is centrosymmetric, the mid-point of the central C-C bond being located on an inversion centre. Two of the three independent nitro groups are disordered over two sites, with a site-occupancy ratio of 0.513 (3):0.487 (3). Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.

The whole mol-ecule of the title compound, C16H18O4, is generated by twofold rotational symmetry; the twofold axis bis-ects the central C-C bond. The O-C-C-O torsion angle about the central C-C bond is 69.45 (16)°. Symmetry-related benzene rings are inclined to one another by 64.91 (8)°. In the crystal, mol-ecules are connected by C-H⋯O hydrogen bonds, forming a three-dimensional network.
