Synthesis, crystal structures and Hirshfeld surface analysis of 1,4-dibenzyl-6-methyl-1,4-di-hydro-quinoxaline-2,3-dione.

ABSTRACT: The title quinoxaline mol-ecule, C23H20N2O2, is not planar, the dihedral angle angle between the mean planes of the benzene rings being 72.54?(15)°. In the crystal, mol-ecules are connected into chains extending parallel to (10) by weak C-H?O hydrogen bonds. Weak C-H?? inter-actions link the chains, forming a three-dimensional network structure. Hirshfeld surface analysis revealed that the most important contributions for the crystal packing are from H?H (48.7%), H?C/C?H (32.0%), H?O/O?H (15.4%), C?C (1.9%), H?N/N?H (1.1%) contacts.

1,4-Dihydro-benzo[g]quinoxaline-2,3-dione.

Project description:The title compound, C12H8N2O2, was prepared by the reaction of the diethyl ester of naphthalene-bis-(oxamate) with tert-BuNH2. The mol-ecule is nearly planar, with an r.m.s. deviation of 0.017?Å from the plane through all 16 non-H atoms. In the crystal, a three-dimensional network is formed, composed of layers of mol-ecules along the b- and c-axis directions, due to the formation of inter-molecular N-H?O hydrogen bonds, as well as of chains along the a-axis direction due to parallel displaced sandwich-type ?-? inter-actions with average distances between the inter-acting mol-ecules in the range 3.35-3.40?Å.

1,4-Dihydroxy-quinoxaline-2,3(1H,4H)-dione.

Project description:The asymmetric unit of the title compound, C(8)H(6)N(2)O(4), contains one half-mol-ecule; a twofold rotation axis bisects the molecule. The quinoxaline ring is planar, which can be attributed to electron delocalization. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the mol-ecules into R(2) (2)(10) motifs, leading to layers, which inter-act via phen-yl-phenyl inter-actions (C?C distances in the range 3.238-3.521?Å).

Crystal structures of two 2,3-di-ethyl-naphtho-[2,3-g]quinoxaline-6,11-dione derivatives.

Project description:Two new 5,12-disubstituted 2,3-di-ethyl-naphtho-[2,3-g]quinoxaline-6,11-dione compounds were readily synthesized from the commercial dye quinizarin. For 2,3-diethyl-5,12-di-hydroxy-naphtho-[2,3-g]quinoxaline-6,11-dione, (II), C20H16N2O4, the mol-ecule displays a near planar conformation and both hy-droxy groups participate in intra-molecular O-H?O(carbon-yl) hydrogen bonds. In the crystal, ?-? ring inter-actions [minimum ring centroid separation = 3.5493?(9)?Å] form stacks of co-planar mol-ecules down the c axis, while only minor inter-molecular C-H?O inter-actions are present. In contrast, in 2,3-diethyl-5,12-bis-(piperidin-1-yl)naphtho-[2,3-g]quinoxaline-6,11-dione, (IV), C30H34N4O2, which contains two independent, but similar, mol-ecules in the asymmetric unit, the polycyclic cores have a significant twist, with dihedral angles of 29.79?(6) and 29.31?(7)° between the terminal rings and only minor inter-molecular C-H?O hydrogen-bonding inter-actions are present. Electron density associated with additional solvent mol-ecules disordered about a fourfold axis was accounted for using the SQUEEZE procedure in PLATON [Spek (2015 ?). Acta Cryst. C71, 9-18].

Crystal structure, DFT study and Hirshfeld surface analysis of 1-nonyl-2,3-di-hydro-1H-indole-2,3-dione.

Project description:In the title mol-ecule, C17H23NO2, the di-hydro-indole portion is planar (r.m.s. deviation = 0.0157 Å) and the nonyl substituent is in an 'extended' conformation. In the crystal, the nonyl chains inter-calate and the di-hydro-indole-dione units are associated through C-H⋯O hydrogen bonds to form micellar blocks. Based on the Hirshfeld surface analysis, the most important inter-molecular inter-action is the H⋯H inter-action.

Crystal structure and Hirshfeld surface analysis of 3,4-di-hydro-2H-anthra[1,2-b][1,4]dioxepine-8,13-dione.

Project description:The title compound, C17H12O4, was synthesized from the dye alizarin. The dihedral angle between the mean plane of the anthra-quinone ring system (r.m.s. deviation = 0.039?Å) and the dioxepine ring is 16.29?(8)°. In the crystal, the mol-ecules are linked by C-H?O hydrogen bonds, forming sheets lying parallel to the ab plane. The sheets are connected through ?-? and C=O?? inter-actions to generate a three-dimensional supra-molecular network. Hirshfeld surface analysis was used to investigate inter-molecular inter-actions in the solid-state: the most important contributions are from H?H (43.0%), H?O/O?H (27%), H?C/C?H (13.8%) and C?C (12.4%) contacts.

Synthesis, crystal structure at 219?K and Hirshfeld surface analyses of 1,4,6-tri-methyl-quinoxaline-2,3(1H,4H)-dione monohydrate.

Project description:The asymmetric unit of the title compound, C11H12N2O2·H2O, contains a mol-ecule of 1,4,6-trimethyl-1,4-di-hydro-quinoxaline-2,3-dione and a solvent water mol-ecule. Four atoms of the benzene ring are disordered over two sets of sites in a 0.706?(7):0.294?(7) ratio while the N-bound methyl groups are rotationally disordered with occupancy ratios of 0.78?(4):0.22?(4) and 0.76?(5):0.24?(5). In the crystal, mol-ecules are linked by O-H?O and C-H?O hydrogen bonds into layers lying parallel to (10). The Hirshfeld surface analysis indicates that the most important contributions to the packing arrangement are due to H?H (51.3%) and O?H/H?O (28.6%) inter-actions. The mol-ecular structure calculated by density functional theory is compared with the experimentally determined mol-ecular structure, and the HOMO-LUMO energy gap has been calculated.

The crystal structures and Hirshfeld surface analyses of four 3,5-diacetyl-2-methyl-2,3-di-hydro-1,3,4-thia-diazol-2-yl derivatives.

Project description:The title compounds, 4-(5-acetamido-3-acetyl-2-methyl-2,3-di-hydro-1,3,4-thia-diazol-2-yl)phenyl benzoate, C20H19N3O4S (I), 4-(5-acetamido-3-acetyl-2-methyl-2,3-di-hydro-1,3,4-thia-diazol-2-yl)phenyl isobutyrate 0.25-hydrate, C17H21N3O4S·0.25H2O (II), 4-(5-acetamido-3-acetyl-2-methyl-2,3-di-hydro-1,3,4-thia-diazol-2-yl)phenyl propionate, C16H19N3O4S (III) and 4-(5-acetamido-3-acetyl-2-methyl-2,3-di-hydro-1,3,4-thia-diazol-2-yl)phenyl cinnamate chloro-form hemisolvate, C22H21N3O4S·0.5CHCl3 (IV), all crystallize with two independent mol-ecules (A and B) in the asymmetric unit in the triclinic P space group. Compound II crystallizes as a quaterhydrate, while compound IV crystallizes as a chloro-form hemisolvate. In compounds I, II, III (mol-ecules A and B) and IV (mol-ecule A) the five-membered thia-diazole ring adopts an envelope conformation, with the tetra-substituted C atom as the flap. In mol-ecule B of IV this ring is flat (r.m.s. deviation 0.044?Å). The central benzene ring is in general almost normal to the mean plane of the thia-diazole ring in each mol-ecule, with dihedral angles ranging from 75.8?(1) to 85.5?(2)°. In the crystals of all four compounds, the A and B mol-ecules are linked via strong N-H?O hydrogen bonds and generate centrosymmetric four-membered R 4 4(28) ring motifs. There are C-H?O hydrogen bonds present in the crystals of all four compounds, and in I and II there are also C-H?? inter-actions present. The inter-molecular contacts in the crystals of all four compounds were analysed using Hirshfeld surface analysis and two-dimensional fingerprint plots.

Crystal structures, Hirshfeld atom refinements and Hirshfeld surface analyses of tris-(4,5-di-hydro-furan-2-yl)methyl-silane and tris-(4,5-di-hydro-furan-2-yl)phenyl-silane.

Project description:The title compounds, C13H18O3Si (1) and C18H20O3Si (2), represent functional-izable di-hydro-furan-ylsilanes, which permit substitution by a variety of nucleophiles. The crystal structures of 1 and 2 display weak inter-molecular C-H?O hydrogen-bonding inter-actions (qu-anti-fied by Hirshfeld surface analysis), leading to a two-dimensional supra-molecular network for 1 and a one-dimensional supra-molecular network for 2. The crystal structures of 1 and 2 were refined both on the basis of the independent atom model (IAM) and the Hirshfeld atom refinement (HAR) approach, and the results are comparatively discussed.

(4-Nitro-phen-yl)methyl 2,3-di-hydro-1H-pyrrole-1-carboxyl-ate: crystal structure and Hirshfeld analysis.

Project description:In the title compound, C12H12N2O4, the di-hydro-pyrrole ring is almost planar (r.m.s. deviation = 0.0049?Å) and is nearly coplanar with the adjacent C2O2 residue [dihedral angle = 4.56?(9)°], which links to the 4-nitro-benzene substituent [dihedral angle = 4.58?(8)°]. The mol-ecule is concave, with the outer rings lying to the same side of the central C2O2 residue and being inclined to each other [dihedral angle = 8.30?(7)°]. In the crystal, supra-molecular layers parallel to (10-5) are sustained by nitro-benzene-C-H?O(carbon-yl) and pyrrole-C-H?O(nitro) inter-actions. The layers are connected into a three-dimensional architecture by ?(pyrrole)-?(nitro-benzene) stacking [inter-centroid separation = 3.7414?(10)?Å] and nitro-O??(pyrrole) inter-actions.
