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, C34H38N4, possesses Ci symmetry. The supramolecular structure is achieved by intramolecular C—HN and weak intermolecular C—Hπ interactions.
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.
