The title compound, C10H12N2O4, crystallizes in the monoclinic non-centrosymmetric space group Pn with Z = 2. The two methyl carbamate groups, —N(H)—C(=O)—OCH3, are twisted away from the aromatic ring mean plane, but form a semiflexible eight-membered cavity involving the atoms of the MeO—C(=O)—N(H)—CH2—CH2—N(H)—C(=O)—OMe group. The NH groups act as hydrogen-bond donors and the C=O groups as acceptors to form intermolecular N—H⋯O hydrogen bonding with an R21(7) motif, generating extended ribbons along the b direction.

In the title compound, C9H8N2O4, the 3-nitro­benz­aldehyde oxime and acetyl group have a dihedral angle of 19.5 (4)°. The acetyl carbonyl and 3-nitro­benz­aldehyde oxime groups both adopt a trans configuration ( E). In the crystal structure, mol­ecules are linked by a series of weak intermolecular C—H⋯O interactions, forming a sheet-like structure parallel to the (303) plane. [ABSTRACT FROM AUTHOR]

The title compound, C14H22N2O6, possesses C i 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—H⋯O 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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

The title compound, C14H10Cl4, possesses C i 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—H⋯π inter­molecular inter­actions. [ABSTRACT FROM AUTHOR]

The title compound, C16H17NO3, crystallizes in the space group P , with one mol­ecule in the asymmetric unit. The amide H atom is engaged in an intramolecular N—H⋯O contact to the O atom of one of the two carbonyl groups. The mol­ecules form centrosymmetric dimers through self-complementary C—H⋯O hydrogen-bonding interactions defining the R22(14)[ R21(6)] motif. The supramolecular structure is achieved by aryl C—H⋯π interactions, as well as face-to-face π–π stacking interactions between lactone and benzenoid rings. [ABSTRACT FROM AUTHOR]

The title compound, C6H12N2S2, possesses a centre of symmetry with one-half of the mol­ecule in the asymmetric unit. The crystal structure has inter­molecular N—H⋯N and C—H⋯S contacts and intra­molecular S⋯N inter­actions. [ABSTRACT FROM AUTHOR]
