organic compounds
The title compound, C14H10Cl4, possesses Ci symmetry and crystallizes with one half-molecule in the asymmetric unit. The two phenyl rings are antiperiplanar and inclined to one another by 180° by symmetry. The central C—C bond distance and the Cl—C—Cl bond angle [1.5887 (18) Å and 106.02 (7)°, respectively] are significantly different from ideal sp3 values. In the crystal, a supramolecular structure is achieved by soft parallel-displaced π–π stacking and C—Hπ intermolecular interactions.
metal-organic compounds
In the crystal structure of the title compound, [Fe2(C12H10P)2(CO)6]·CH2Cl2, the complex molecule lies across a mirror plane. Two diphosphide ligands bridge two (CO)3Fe fragments to form a dinuclear complex, in which the Fe—Fe distance is 2.6701 (6) Å. Two aromatic rings within the same molecule interact by face-to-face π–π stacking, with a centroid-to-centroid distance of 3.601 (2) Å.
organic compounds
The title compound, C14H22N2O6, possesses Ci symmetry and crystallizes with one half-molecule in the aymmetric unit. The structure can be described as cyclohexyldiamide singly bonded to two ethyl carboxylate groups. The supramolecular structure is achieved through intermolecular hard N—HO hydrogen-bonding interactions involving only the amide group. The full hydrogen-bonding network is described by the C22(8)[S(5)S(5)C(4)] motif that develops along the c-axis direction.
