3,3'-(p-Phenyl-ene)bis-(3,4-dihydro-2H-1,3-benzoxazine).

ABSTRACT: Mol-ecules of the title compound, C(22)H(20)N(2)O(2), are situated on crystallographic centres of symmetry. The oxazinane ring adopts a sofa conformation. Mol-ecules are linked into cyclic centrosymmetric dimers via C-H?O hydrogen bonds with the motif R(2) (2)(6). In addition to the C-H?O inter-actions, the crystal structure is also stabilized by C-H?? inter-actions.

Mol-ecules of the title compound, C(22)H(20)N(2)O(2), are situated on crystallographic centres of symmetry. The oxazinane ring adopts a sofa conformation. Mol-ecules are linked into cyclic centrosymmetric dimers via C-H⋯O hydrogen bonds with the motif R(2) (2)(6). In addition to the C-H⋯O inter-actions, the crystal structure is also stabilized by C-H⋯π inter-actions. ...[more]

3,3'-(Ethane-1,2-di-yl)bis-(3,4-dihydro-2H-1,3-benzoxazine).

Project description:The title compound, C(18)H(20)N(2)O(2), was prepared by Mannich-type reaction of phenol, ethane-1,2-diamine and formaldehyde. The heterocyclic rings adopt half-chair conformations. The acyclic methyl-ene groups attached to the N atoms are in an axial position. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into dimers. These dimers are further connected via C-H?? contacts.

3,3'-(Ethane-1,2-di-yl)bis-(6-methyl-3,4-dihydro-2H-1,3-benzoxazine).

Project description:The asymmetric unit of the title compound, C(20)H(24)N(2)O(2), contains one half-mol-ecule, which is completed by inversion symmetry. In the crystal, mol-ecular chains are formed through non-classical C-H⋯O hydrogen bonds, formed between axial H atoms of the oxazine ring and a O atom of a neighboring mol-ecule.

3,3'-Ethyl-enebis(3,4-dihydro-6-chloro-2H-1,3-benzoxazine).

Project description:The asymmetric unit of the title compound, C(18)H(18)Cl(2)N(2)O(2), contains one half of an independent mol-ecule, the other half being generated via a centre of inversion at the mol-ecular centroid. In the crystal structure, mol-ecular chains are formed through non-classical C-H? O hydrogen bonds between an axial H atom of the oxazine ring and the O atom of a neighbouring mol-ecule.

3,3'-(Ethane-1,2-diyl)bis(6-meth-oxy-3,4-dihydro-2H-1,3-benzoxazine) mono-hydrate.

Project description:The asymmetric unit of the title compound, C(20)H(24)N(2)O(4)·H(2)O, contains one half-organic mol-ecule (an inversion centre generates the other half of the mol-ecule) and a half-mol-ecule of water (the O atom has site symmetry 2). The near planarity of the fused-benzene ring is illustrated by the very small deviations of all the atoms from the plane [largest deviation = 0.0092 (11) Å. The six-membered N,O-containing ring adopts a half-chair conformation. The observed N-CH(2) and CH(2)-O bond lengths can be correlated to the manifestation of an anomeric effect in the N-CH(2)-O unit. In the crystal, the mol-ecules are connected into zigzag chains parallel to [001] through O-H⋯N hydrogen bonds formed between the oxazinic N atom and the solvent water mol-ecule. The chains are consolidated by C-H⋯O inter-actions.

3,3-Dimethyl-9-phenyl-3,4-dihydro-acridin-1(2H)-one.

Project description:In the mol-ecule of the title compound, C(21)H(19)NO, the terminal saturated six-membered ring of the dihydro-acridine unit adopts an envelope conformation, while the other two fused rings are nearly coplanar, with a dihedral angle of 2.61 (3)°. The coplanar ring system is oriented with respect to the phenyl ring at a dihedral angle of 74.58 (3)°. In the crystal structure, there is a C-H⋯π contact between the central ring of the dihydro-acridine system and the phenyl ring and a π-π contact between the two central rings [centroid-centroid distance = 3.809 (1) Å].

In the crystal, weak C-H⋯F inter-actions link the mol-ecules into a two-dimensional network parallel to (001).

Project description:In the title compound, C(32)H(36)N(4) (2+)·2PF(6) (-), the cation and the anions each have crystallographic twofold rotation symmetry.

The cyclo-pentyl ring adopts a half-chair conformation. In the crystal, mol-ecules are linked into a three-dimensional network through C-H?F hydrogen bonds. A C-H?? inter-action is also observed.

Project description:In the mol-ecule of the title compound, C(20)H(16)N(2)O(2), two intra-molecular N-H?O inter-actions occur. The mol-ecular chains are linked by N-H?? and C-H?? inter-actions into a three-dimensional network, which seems to be very effective in the stabilization of the crystal structure.

1,1'-[(2-Phenyl-2,3-dihydro-1H-benz-imidazole-1,3-di-yl)bis-(methyl-ene)]bis-(1H-benzotriazole).

Project description:The imidazole ring in the title compound, C(27)H(22)N(8), adopts a slight envelope conformation with the C atom carrying the phenyl ring being the flap atom. The phenyl ring is almost perpendicular to the mean plane of the imidazole ring [dihedral angle = 88.90 (7)°]. The (1H-benzotriazol-1-yl)methyl groups bound to the imidazole ring are positioned on the same side of the imidazole ring. The dihedral angle between these benzotriazolyl rings is 17.71 (5)°. The crystal packing is stabilized by a C-H⋯π inter-action, which connects the mol-ecules into zigzag chains running along the b axis.
