ABSTRACT
The title compound, C21H22N2O, crystallizes with two independent mol-ecules in the asymmetric unit. In both mol-ecules, the anthracene ring systems are almost planar, with maximum deviations of 0.071â (8) and 0.028â (7)â Å, and make dihedral angles of 73.4â (2) and 73.3â (2)° with the least-squares planes formed by the four C atoms of the morpholine rings, which adopt a chair conformation. An intra-molecular C-Hâ¯π inter-action occurs. In the crystal, the packing is stabilized by weak C-Hâ¯O hydrogen bonds, which connect pairs of molecules into parallel to the c axis, and C-Hâ¯π inter-actions.
ABSTRACT
In the title compound, C19H25N5O2, the morpholine ring has a chair conformation. The plane of the central benzene ring makes dihedral angles of 88.75â (12) and 60.02â (7)°, respectively, with the mean plane formed by the four planar C atoms of the morpholine ring and with the plane of the triazole ring. In the crystal, mol-ecules are linked via C-Hâ¯π inter-actions, forming slabs lying parallel to (10-1). The C atoms of the bridging ethyl-ene group, between the morpholine and benzene rings, and the terminal ethene group of the prop-1-ene substituent attached to the triazole ring, are disordered over two sets of sites, with an occupancy ratio of 0.634â (13):0.366â (13).
ABSTRACT
The triazole ring of the title compound, C20H20N4O, is normal to the central benzene ring, making a dihedral angle of 90.0â (3)°, and forms a dihedral angle of 69.2â (3)° with the terminal phenyl ring. The dihedral angle between the phenyl and benzene rings is 88.2â (3)°. The atoms of the terminal propenyl group are disordered over two sets of sites, with a site-occupancy ratio of 0.663â (13):0.337â (13). In the crystal, C-Hâ¯N contacts lead to the formation of a layer structure extending parallel to (011). Two weak C-Hâ¯π inter-actions are also observed.
ABSTRACT
The asymmetric unit of the title compound, C17H21N5O2, contains two crystallographically independent mol-ecules, which are linked by a C-Hâ¯N hydrogen bond. The morpholine rings of both mol-ecules adopt distorted chair conformations. The dihedral angles between the triazole and benzene rings are 12.8â (3)° in the first independent molecule in which the -N=C- group between the morpholine and benzene rings is disordered [site-occupancy ratio = 0.576â (7):0.424â (7)] and 88.1â (2)° in the second independent mol-ecule. In the crystal, mol-ecules are linked by C-Hâ¯N hydrogen bonds along the [100] direction. In addition, one weak C-Hâ¯π inter-action and two weak π-π stacking inter-actions [centroid-centroid distances = 3.840â (3) and 3.823â (2)â Å] between the triazole rings of adjacent mol-ecules are observed. The atoms of the terminal propenyl groups in both mol-ecules are disordered over two sets of sites [site-occupancy ratios = 0.691â (10):0.309â (10) and 0.705â (15):0.295â (15)].
ABSTRACT
The title compound, C16H23N3O3, contains two morpholine rings, each of which adopts a chair conformation. The mol-ecular conformation is stabilized by an intra-molecular O-Hâ¯N hydrogen bond, leading to a S(6) ring. In the crystal, mol-ecules are linked into zigzag chains along the c-axis direction by C-Hâ¯O and C-Hâ¯π inter-actions.
ABSTRACT
In the title compound, C20H18N4O3, the dihedral angles between the central benzene ring and the 1H-1,2,3-triazole ring and the fused benzene ring are 65.34â (19) and 3.64â (18)°, respectively. The dioxole ring adopts a shallow envelope conformation, with the methyl-ene C atom displaced by 0.156â (5)â Å from the other four atoms (r.m.s. deviation = 0.007Å). In the crystal, the mol-ecules are linked by C-Hâ¯O and C-Hâ¯N hydrogen bonds, generating a three-dimensional network.
ABSTRACT
In the title compound, C(22)H(24)N(4)O, the terminal and central benzene rings make dihedral angles of 52.7â (3) and 43.8â (2)°, respectively, with the triazole ring. The dihedral angle between the benzene rings is 8.9â (2)°. The crystal structure features C-Hâ¯π inter-actions. The atoms of the terminal propenyl group are disordered over two sets of sites, with a refined occupancy ratio of 0.714â (14):0.286â (14).
ABSTRACT
In the title compound, C(21)H(22)N(4)O(3), the triazole ring is planar [maximum deviaton = 0.004â (1)â Å] and makes dihedral angles of 26.21â (8) and 38.66â (8)° with the two benzene rings. In the crystal, mol-ecules are linked by C-Hâ¯O hydrogen bonds, forming zigzag chains along [1-11]. In addition, a weak C-Hâ¯π intreraction is also observed.
