6-Methyl-2-oxo-N-(quinolin-6-yl)-2H-chromene-3-carboxamide: crystal structure and Hirshfeld surface analysis.

ABSTRACT: The title coumarin derivative, C20H14N2O3, displays intra-molecular N-H?O and weak C-H?O hydrogen bonds, which probably contribute to the approximate planarity of the mol-ecule [dihedral angle between the coumarin and quinoline ring systems = 6.08?(6)°]. The supra-molecular structures feature C-H?O hydrogen bonds and ?-? inter-actions, as confirmed by Hirshfeld surface analyses.

The title coumarin derivative, C20H14N2O3, displays intra-molecular N-H⋯O and weak C-H⋯O hydrogen bonds, which probably contribute to the approximate planarity of the mol-ecule [dihedral angle between the coumarin and quinoline ring systems = 6.08 (6)°]. The supra-molecular structures feature C-H⋯O hydrogen bonds and π-π inter-actions, as confirmed by Hirshfeld surface analyses. ...[more]

Crystal structures of 4-methyl-2-oxo-2H-chromene-7,8-diyl di-acetate and 4-methyl-2-oxo-2H-chromene-7,8-diyl bis-(pent-4-ynoate).

Project description:In the structures of the two title coumarin derivatives, C14H12O6, (1), and C20H16O6, (2), one with acetate and the other with pent-4-ynoate substituents, both the coumarin rings are almost planar. In (1), both acetate substituents are significantly rotated out of the coumarin plane to minimize steric repulsions. One acetate substituent is disordered over two equivalent conformations, with occupancies of 0.755?(17) and 0.245?(17). In (2), there are two pent-4-ynoate substituents, the C C group of one being disordered over two positions with occupancies of 0.55?(2) and 0.45?(2). One of the pent-4-ynoate substituents is in an extended conformation, while the other is in a bent conformation. In this derivative, the planar part of both pent-4-ynoate substituents deviate from the coumarin plane. The packing of (1) is dominated by ?-? stacking involving the coumarin rings and weak C-H?O contacts link the parallel stacks in the [101] direction. In contrast, in (2) the packing is dominated by R 2 (2)(24) hydrogen bonds, involving the acidic sp H atom and the oxo O atom, which link the mol-ecules into centrosymmetric dimers. The bent conformation of one of the pent-4-ynoate substituents prevents the coumarin rings from engaging in ?-? stacking.

2-[(2,4,6-Tri-methyl-benzene)-sulfon-yl]phthalazin-1(2H)-one: crystal structure, Hirshfeld surface analysis and computational study.

Project description:The X-ray crystal structure of the title phthalazin-1-one derivative, C17H16N2O3S {systematic name: 2-[(2,4,6-tri-methyl-benzene)-sulfon-yl]-1,2-di-hydro-phthalazin-1-one}, features a tetra-hedral sulfoxide-S atom, connected to phthalazin-1-one and mesityl residues. The dihedral angle [83.26?(4)°] between the organic substituents is consistent with the mol-ecule having the shape of the letter V. In the crystal, phthalazinone-C6-C-H?O(sulfoxide) and ?(phthalazinone-N2C4)-?(phthalazinone-C6) stacking [inter-centroid distance = 3.5474?(9)?Å] contacts lead to a linear supra-molecular tape along the a-axis direction; tapes assemble without directional inter-actions between them. The analysis of the calculated Hirshfeld surfaces confirm the importance of the C-H?O and ?-stacking inter-actions but, also H?H and C-H?C contacts. The calculation of the inter-action energies indicate the importance of dispersion terms with the greatest energies calculated for the C-H?O and ?-stacking inter-actions.

Polymorphism in the structure of N-(5-methyl-thia-zol-2-yl)-4-oxo-4H-chromene-3-carboxamide.

Project description:Chromone derivatives have been extensively studied recently because of to their promising biological activities. The new title chromone-thia-zole hybrid presented here, C14H10N2O3S, is a candidate as a selective ligand for adenosine receptors. The compound has been synthesized and characterized by the usual spectroscopic means (NMR and EM/IE) and its structure elucidated by X-ray crystallography, which revealed the presence of packing polymorphism. The two polymorphs (one with space group P21/n and one with P21/c) show slightly different conformations and the major change induced by crystallization regards the intra-molecular contacts defining the supra-molecular structure. Those differences been highlighted by Hirshfeld surface analysis mapped over dnorm and ESP.

N-(2-Oxo-2H-chromen-3-yl)cyclo-hexane-carboxamide.

Project description:In the title compound, C16H17NO3, the coumarin moiety is essentially planar [maximum deviation from the mean plane formed by the C and O atoms of the coumarin = 0.0183?(12)?Å] and that the cyclo-hexane ring adopts the usual chair conformation. The dihedral angle between the mean plane of the coumarin residue and the plane of the amide residue (defined as the N, C and O atoms) is 18.9?(2)°. There are two intra-molecular hydrogen bonds involving the amide group. In one, the N atom acts as donor to the ketonic O atom and in the other, the amide O atom acts as acceptor of a C-H group of the coumarin. In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H?O contacts and these dimers are linked into pairs by weak C-H?O hydrogen bonds. The combination of these inter-actions creates a chain of rings which runs parallel to [2-10]. C-H?? and ?-? [centroid-centroid distance = 3.8654?(10)?Å] inter-actions are also observed.

Ethyl 2-(4-benzyl-3-methyl-6-oxo-1,6-dihydropyridazin-1-yl)acetate: crystal structure and Hirshfeld surface analysis.

Project description:The title compound, C16H18N2O3, is constructed about a central oxopyridazinyl ring (r.m.s. deviation = 0.0047?Å), which is connected to an ethyl-acetate group at the N atom closest to the carbonyl group, and benzyl and methyl groups second furthest and furthest from the carbonyl group, respectively. An approximately orthogonal relationship exists between the oxopyridazinyl ring and the best plane through the ethyl-acetate group [dihedral angle = 77.48?(3)°]; the latter lies to one side of the central plane [the Nr-Nr-Cm-Cc (r = ring, m = methyl-ene, c = carbon-yl) torsion angle being 104.34?(9)°]. In the crystal, both H atoms of the N-bound methyl-ene group form methyl-ene-C-H?O(ring carbon-yl) or N(pyridazin-yl) inter-actions, resulting in the formation of a supra-molecular tape along the a-axis direction. The tapes are assembled into a three-dimensional architecture by methyl- and phenyl-C-H?O(ring carbon-yl) and phenyl-C-H?O(ester carbon-yl) inter-actions. The analysis of the calculated Hirshfeld surface indicates the dominance of H?H contacts to the overall surface (i.e. 52.2%). Reflecting other identified points of contact between mol-ecules noted above, O?H/H?O (23.3%), C?H/H?C (14.7%) and N?H/H?N (6.6%) contacts also make significant contributions to the surface.

Crystal structure and Hirshfeld surface analysis of (E)-1-[(4,7-di-methyl-quinolin-2-yl)methyl-idene]semicarbazide dihydrate.

Project description:In the title compound, C13H14N4O·2H2O, the organic mol-ecule is almost planar. In the crystal, the mol-ecules are linked by O-H?O, N-H?O and O-H?N hydrogen bonds, forming a two-dimensional network parallel to (10). Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H?H (55.4%), H?O/O?H (14.8%), H?C/C?H (11.7%) and H?N/N?H (8.3%) inter-actions.

Crystal structure and Hirshfeld surface analysis of 1-(2,4-di-chloro-benz-yl)-5-methyl-N-(thio-phene-2-sulfon-yl)-1H-pyrazole-3-carboxamide.

Project description:In the title compound, C16H13Cl2N3O3S2, the thio-phene ring is disordered in a 0.762?(3):0.238?(3) ratio by an approximate 180° rotation of the ring around the S-C bond linking the ring to the sulfonyl unit. The di-chloro-benzene group is also disordered over two sets of sites with the same occupancy ratio. The mol-ecular conformation is stabilized by intra-molecular C-H?Cl and C-H?N hydrogen bonds, forming rings with graph-set notation S(5). In the crystal, pairs of mol-ecules are linked by N-H?O and C-H?O hydrogen bonds, forming inversion dimers with graph-set notation R22(8) and R12(11), which are connected by C-H?O hydrogen-bonding inter-actions into ribbons parallel to (100). The ribbons are further connected into a three-dimensional network by C-H?? inter-actions and ?-? stacking inter-actions between benzene and thio-phene rings, with centroid-to-centroid distances of 3.865?(2), 3.867?(7) and 3.853?(2)?Å. Hirshfeld surface analysis has been used to confirm and qu-antify the supra-molecular inter-actions.

Crystal structure, Hirshfeld surface analysis and DFT studies of ethyl 2-{4-[(2-eth-oxy-2-oxoeth-yl)(phen-yl)carbamo-yl]-2-oxo-1,2-di-hydro-quinolin-1-yl}acetate.

Project description:The title com-pound, C24H24N2O6, consists of ethyl 2-(1,2,3,4-tetra-hydro-2-oxo-quinolin-1-yl)acetate and 4-[(2-eth-oxy-2-oxoeth-yl)(phen-yl)carbomoyl] units, where the oxo-quinoline unit is almost planar and the acetate substituent is nearly perpendicular to its mean plane. In the crystal, C-HOxqn?OEthx and C-HPh-yl?OCarbx (Oxqn = oxoquinolin, Ethx = eth-oxy, Phyl = phenyl and Carbx = carboxyl-ate) weak hydrogen bonds link the mol-ecules into a three-dimensional network sturucture. A ?-? inter-action between the constituent rings of the oxo-quinoline unit, with a centroid-centroid distance of 3.675?(1)?Å may further stabilize the structure. Both terminal ethyl groups are disordered over two sets of sites. The ratios of the refined occupanies are 0.821?(8):0.179?(8) and 0.651?(18):0.349?(18). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H?H (53.9%), H?O/O?H (28.5%) and H?C/C?H (11.8%) inter-actions. Weak inter-molecular hydrogen-bond inter-actions and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Density functional theory (DFT) geometric optimized structures at the B3LYP/6-311G(d,p) level are com-pared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO mol-ecular orbital behaviour was elucidated to determine the energy gap.
