The crystal structure of the title compound, [Zn(C46H24N8)(CH4O)], consists of two‐dimensional supramolecular arrays sustained by O—H⋯N(pyridyl) hydrogen bonding and weak Zn⋯NC coordination. The interlayer organization in the crystal structure is characterized by tight stacking of the corrugated layers. 相似文献

In the molecule of the title compound, C11H10INO2, the phthalimide group is not exactly planar. The dihedral angle between the mean planes of the phthalimide and iodopropyl moieties is 76.6 (2)°. The structure is stabilized by intermolecular C—H?O and C—H?I interactions, and an intermolecular I?O interaction of 3.571 (4) Å, the latter linking the molecules into infinite chains. 相似文献

The title compound, 3,3′‐(4‐pyridylimino)dipropanenitrile, C11H12N4, has a twofold axis and consists of a pyridine ring head and two cyanoethyl tails, the three groups being linked by an N atom. The planar geometry around the amino N atom suggests conjugation with the π‐system of the pyridine ring. The molecules are stacked in a layer structure via relatively weak to very weak intermolecular C—H⃛π and C—H⃛N hydrogen‐bond interactions. 相似文献

Tris[2‐(benzoylamino)ethyl]amine [alternatively, N,N′,N′′‐(nitrilotriethyl)tribenzamide], C27H30N4O3, adopts a folded structure, forming a symmetrical cavity with an average depth of 7.3 Å and width ranging from 4.1–4.4 Å. The folded structure is a result of one intramolecular N—H?O hydrogen bond. A linear chain motif along the c axis best describes the extended intermolecular N—H?O hydrogen bonding. 相似文献

The title compound, C10H8F5NO, crystallizes as a racemate with four symmetry‐independent molecules in the asymmetric unit. The four molecules form two hydrogen‐bonded pairs. Each pair is a building unit of an independent C(4) chain propagating parallel to the ab plane. 相似文献

The title compound, raloxifene hydrochloride, C28H28NO4S+·Cl?, belongs to the benzothiophene class of antiosteoporotic drugs. In the molecular cation, the 2‐phenol ring sustains a dihedral angle of 45.3 (1)° relative to the benzo[b]thiophene system. The benzo[b]thiophene and phenyl ring planes are twisted with respect to the carbonyl plane, with the smallest twist component occurring between the phenyl and carbonyl planes. The N atom bears the positive charge in the molecular cation and the piperidine ring adopts an almost perfect chair conformation. The Cl? anion is involved in the formation of N—H?Cl and O—H?Cl intermolecular hydrogen bonds, which lead to the formation of a layer of molecular cations. 相似文献

In the title compound, C17H20N2O3, the cyclobutane ring is puckered, with a dihedral angle of 19.11 (15)°. The 1‐phenyl and 3‐[1‐hydroxyimino‐2‐(succinimido)ethyl] groups are in cis positions. The molecules are linked by O—H⋯O and C—H⋯π(benzene) interactions, forming a two‐dimensional network. 相似文献

In ethyl N‐[2‐(hydroxyacetyl)phenyl]carbamate, C11H13NO4, all of the non‐H atoms lie on a mirror plane in the space group Pnma; the molecules are linked into simple chains by a single C—H⋯O hydrogen bond. The molecules of ethyl N‐[2‐(hydroxyacetyl)‐4‐iodophenyl]carbamate, C11H12INO4, are linked into sheets by a combination of O—H⋯I and C—H⋯O hydrogen bonds and a dipolar I⋯O contact. Ethyl N‐[2‐(hydroxyacetyl)‐4‐methylphenyl]carbamate, C12H15NO4, crystallizes with Z′ = 2 in the space group P; pairs of molecules are weakly linked by an O—H⋯O hydrogen bond and these aggregates are linked into chains by two independent aromatic π–π stacking interactions. 相似文献

The title compounds, C19H19I2NO3 and C19H19Br2NO3, are derivatives of α‐aminoisobutyric acid with halogen substituents at the para and meta positions, respectively. The ethoxycarbonyl and formamide side chains attached to the Cα atom of the molecule adopt extended and folded conformations, respectively. The crystal structures are stabilized by N—H⃛O, C—H⃛O, C—Br⃛O and C—I⃛O interactions. 相似文献

The crystal structure of racemic Venlafaxine hydrochloride, C17H28NO2+·Cl?, consists of two types of parallel chains formed by translated Venlafaxine+ cations, hydrogen bonded by Cl? anions, and characterized by the opposite chirality of their constituent molecules. These chains organize in two different types of broad layers of opposite handedness, related by a glide plane. 相似文献

The title compound, 2,2′‐(3‐oxapentane‐1,5‐diyldioxy)diphenol, crystallizes as a methanol solvate, C16H18O5·CH4O. The methanol molecule, roughly perpendicular to the mean plane of the polyether molecule, is hydrogen bonded to the two polyether OH groups and to the central ether O atom. Possible C—H?π intermolecular interactions are present. 相似文献

The title compound, C21H24FN2O2+·Cl−·C3H8O, is a potential drug designed as a hybrid compound with antihypertensive, antioxidant and β‐adrenolytic activity. The cation contains nearly planar benzofuran and fluorophenyl ring systems, as well as a piperazine ring adopting an almost perfect chair conformation. The benzofuran and piperazine moieties are connected by an ethyl chain, the moieties forming a dihedral angle of 163.12 (13)°. In the crystal structure, ions and propanol solvent molecules are linked via N—H⋯Cl and O—H⋯Cl bonds into linear (010) chains. 相似文献

The crystal structure of the title compound, C19H26NO+·Cl? (common name: N,N‐diethyl‐2‐[(4‐phenylmethyl)phenoxy]‐ethanamine hydrochloride), contains one molecule in the asymmetric unit. The planes through the two phenyl rings are roughly perpendicular. Protonation occurs at the N atom, to which the Cl? ion is linked via an N—H?Cl hydrogen bond. The molecule adopts an eclipsed rather than extended conformation. 相似文献

(Z)‐3‐(1H‐Indol‐3‐yl)‐2‐(3‐thienyl)acrylonitrile, C15H10N2S, (I), and (Z)‐3‐[1‐(4‐tert‐butylbenzyl)‐1H‐indol‐3‐yl]‐2‐(3‐thienyl)acrylonitrile, C26H24N2S, (II), were prepared by base‐catalyzed reactions of the corresponding indole‐3‐carboxaldehyde with thiophene‐3‐acetonitrile. 1H/13C NMR spectral data and X‐ray crystal structures of compounds (I) and (II) are presented. The olefinic bond connecting the indole and thiophene moieties has Z geometry in both cases, and the molecules crystallize in space groups P21/c and C2/c for (I) and (II), respectively. Slight thienyl ring‐flip disorder (ca 5.6%) was observed and modeled for (I). 相似文献

In the title compound, C13H14BN3O, the aziridine ring is an almost equilateral triangle, the C—C distance being slightly shorter than the C—N distances, probably because of the dative B—N bond. The five‐membered ring, composed of two C atoms and N, B and O atoms, is fused with the aziridine ring to form a six‐membered ring with a chair conformation. 相似文献

The title compound, C16H19NO5, crystallizes as a centrosymmetric dimer through strong O—H⋯O hydrogen‐bonding interactions between the hydroxyphenyl and morpholinocarbonyl groups. The morpholinocarbonyl group is almost perpendicular to the propenoate moiety. Electron delocalization in the N—C(=O) fragment leads to the formation of hydrogen‐bonded S(5) ring motifs through C—H⋯O interactions. 相似文献
