1-[4-(4-Chlorophenyl)piperazin-1-yl]-3-(6-oxo-3,4-diphenyl-1, 6-dihydropyridazin-1-yl)propan-1-one
(2012-09-01) Aydn A.; Akkurt M.; Doǧruer D.S.; Büyükgüngör O.
In the title compound, C29H27ClN4O 2, the six-membered ring of the pyridazine group is nearly planar [maximum deviation = -0.062 (2) Å] and its mean plane makes dihedral angles of 43.05 (9), 44.71 (10) and 72.57 (9)°, respectively, with the two phenyl and benzene rings. The piperazine ring has a chair conformation and its mean plane is almost perpendicular to the attached benzene ring, with a dihedral angle of 83.20 (16)°. In the crystal, molecules are linked via two pairs of C - H⋯O interactions, which result in the formation of chains propagating along [101̄]. Neighbouring chains are linked via C - H⋯π interactions.
2-(6-Benzoyl-2-oxo-1,3-benzothiazol-3-yl)acetic acid
(2010-01-22) Aydn A.; Akkurt M.; Önkol T.; Büyükgüngör O.; Şahin M.F.
In the title compound, C16H11NO4S, the nine-membered fused ring is nearly planar, with maximum deviations from the mean plane of-0.022 (1) Å for the N atom and 0.011 (1) Å for the S atom, and makes a dihedral angle of 53.56 (7)° with the phenyl ring. The crystal structure is stabilized by O-H⋯O and C-H⋯O hydrogen-bonding inter-actions.
2-[2-(4-Benzyl-piperazin-1-ylcarbon-yl)eth-yl]-5,6-diphenyl-pyridazin-3(2H) -one
(2008-12-12) Aydn A.; Doruer D.S.; Akkurt M.; Büyükgüngör O.
The title compound, C30H30N4O2, has a non-planar conformation, the dihedral angles formed by the pyridazinone ring plane and the three phenyl rings being 54.61 (7), 51.10 (7) and 59.53 (8)°. The piperazine ring adopts a chair conformation. Inter- and intra-molecular C - H⋯O contacts are found in the crystal structure and these consolidate the three-dimensional packing.
3-({4-[(2-Methylbenzylidene)amino]-5-sulfanylidene-1H-1,2,4-triazol-3-yl} methyl)-1,3-benzoxazol-2(3H)-one
(2013-02-01) Aydn A.; Hekimoǧlu N.; Akkurt M.; Önkol T.; Çiçekli S.U.; Büyükgüngör O.
In the title compound, C18H15N5O2S, a weak intramolecular C - H⋯S hydrogen bond results in a small dihedral angle of 3.71 (9)° between the methylphenyl and triazole rings, which, in turn, form dihedral angles of 80.09 (8) and 77.32 (8)°, respectively, with the benzoxazolone mean plane. In the crystal, N - H⋯O hydrogen bonds link molecules into chains along [001], and weak C - H⋯N hydrogen bonds and π-π interactions between the five- and six-membered rings [centroid-centroid distances = 3.5074 (11) and 3.616 (1) Å] consolidate the crystal packing.
4-[(2E)-2-(4-Chlorobenzylidene)hydrazinylidene]-1-methyl-1, 4-dihydro-pyridine monohydrate
(2010-06-11) Aydn A.; Akkurt M.; Alptüzün V.; Büyükgüngör O.; Holzgrabe U.; Radacki K.
In the title compound, C13H12ClN3· H2O, the organic mol-ecule is almost planar, with a dihedral angle of 3.22 (10)° between the benzene and pyridine rings. The crystal structure is stabilized by O - H⋯N and C - H⋯O hydrogen bonding and π-π stacking inter-actions [centroid-centroid distances = 3.630 (1) and 3.701 (1) Å].
N-(2-Benzoylethyl)propan-2-aminium chloride
(2012-09-01) Aydn A.; Akkurt M.; Gul H.I.; Mete E.; Sahin E.
In the title salt, C12H18NO+· Cl-, N - H⋯Cl interactions between the free chloride anions and the organic cations connect the molecules into hydrogen-bond dimers, forming a R22(8) motif. The dimers are linked by C - H⋯O hydrogen bonds into chains extending along [301]. The carbonyl group is co-planar with the phenyl ring [C - C - C=O torsion angle = -3.3 (7)°]. The side chain has an E conformation.
N-[2-(4-Methylbenzoyl)ethyl]propan-2-aminium chloride
(2012-09-01) Aydn A.; Akkurt M.; Gul H.I.; Mete E.; Sahin E.
In the title compound, C13H20NO+· Cl-, the protonated amino N atom is hydrogen bonded to the chloride anion. N - H⋯Cl hydrogen bonds link the anions and cations into dimers, which are connected by C - H⋯O hydrogen bonds, forming supra-molecular chains extending along [100].
