1-Methyl-2-(4-methyl-phen-yl)-4-morpholinopyridazine-3,6(1H,2H)-dione.

ABSTRACT: The structure analysis of the title compound, C(16)H(19)N(3)O(3), has been undertaken in order to facilitate the inter-pretation of (1)H and (13)C NMR data and to determine the position of the morpholine residue in this nucleophilic substitution product. The main result is that the morpholine group, with a chair conformation, is connected at the 4-position of the pyridazine ring. The benzene and pyridazine rings make a dihedral angle of 62.17?(5)°. Mol-ecules are linked into a two-dimensional network by non-classical C-H?O hydrogen bonds, in which O atoms serve as double or triple acceptors.

2-(2,3-Dimethyl-phen-yl)-1H-isoindole-1,3(2H)-dione.

Project description:In the title compound, C(16)H(13)NO(2), the 2,3-dimethyl-phenyl group and the 1H-isoindole-1,3(2H)-dione group are essentially planar, with r.m.s. deviations of 0.006 and 0.013 Å, respectively, and are oriented at an angle of 78.19 (3)° with respect to each other. In the crystal, weak C-H⋯O inter-actions link the mol-ecules, forming a zigzag chain parallel to the b axis. Futhermore, C-H⋯π inter-actions are present between the C-H group of isoindole and the 2,3-dimethyl-phenyl benzene ring. The H atoms of the ortho-methyl group are statistically disordered over two positions. Such disorder might be related to the antagonism between intra-molecular steric repulsions and inter-molecular C-H⋯O inter-actions.

2-(2-Meth-oxy-phen-yl)-1H-isoindole-1,3(2H)-dione.

Project description:In the title compound, C(15)H(11)NO(3), the dihedral angle between the meth-oxy-benzene and isoindole ring systems is 70.21?(3)°. The meth-oxy C atom is close to being coplanar with its attached ring [deviation = 0.133?(2)?Å] and is oriented away from the isoindole moiety. In the crystal, inversion dimers linked by pairs of C-H?O hydrogen bonds generate R(2) (2)(10) loops. Further C-H?O inter-actions lead to (010) infinite sheets and weak aromatic ?-? stacking [centroid-centroid separations = 3.6990?(10) and 3.7217?(10)?Å] is also observed.

The pyran and benzene rings are almost perpendicular to each other, making a dihedral angle of 86.32?(2)°. In the crystal, molecules are linked via pairs of O-H?O hydrogen bonds, forming inversion dimers.

Project description:The title compound, C(31)H(25)NO(6), has a structure related to other 3,4-diaryl-substituted maleic anhydride derivatives which have been shown to be useful as photochromic materials. The dihedral angles between the maleimide ring system and the benzene rings bonded to it are 44.48?(3) and 17.89?(3)°, while the angles between each of the latter rings and the corresponding ether bridging connected meth-oxy-benzene rings are 78.61?(8) and 72.67?(7)°.

Project description:In the title compound, C(23)H(24)N(2)O(7), the central 4H-pyran ring adopts a flattened boat conformation, whereas both cyclo-hexenone rings adopt envelope conformations, the C atom bearing the dimethyl substituent being the flap atom in each case. The mean and maximum deviation of the pyran ring are 0.0379?(4) and 0.0605?(3)?Å. The mean plane of the pyran ring and the dinitro-benzene ring make a dihedral angle of 85.88?(2)°.

10-(4-Chloro-phen-yl)-9-(4-fluoro-phen-yl)-3,3,6,6-tetra-methyl-3,4,6,7,9,10-hexa-hydro-acridine-1,8(2H,5H)-dione.

Project description:The title compound, C(29)H(29)ClFNO(2), was synthesized by the reaction of 4-fluoro-benzaldehyde, 5,5-dimethyl-cyclo-hexane-1,3-dione and 3-(4-chloro-phenyl-amino)-5,5-dimethyl-cyclo-hex-2-enone in an ionic liquid (1-butyl-3-methyl-imidazolium bromide). X-ray analysis reveals that the 1,4-dihydro-pyridine ring adopts a boat conformation, while each of the attached partially saturated six-membered rings adopts a half-chair conformation. The structure is stabilized by weak C-H?O and C-H?F hydrogen bonds. The mol-ecule has approximate mirror symmetry; the largest deviation from this symmetry concerns the fluoro- and chloro-phenyl rings.

4-[(Ethoxy-imino)(phen-yl)meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one.

Project description:In the mol-ecule of the title compound, C(19)H(19)N(3)O(2), the central pyrazole ring makes dihedral angles of 9.89?(3) and 66.06?(5)° with the two phenyl rings, and the two phenyl rings form an angle of 74.05?(5)°.

In the crystal structure, inter-molecular N-H?O and C-H?O hydrogen bonds link each mol-ecule to two others, forming an infinite one-dimensional supra-molecular structure along the c axis.
