Crystal structure of 5-bromo-1-ethyl-indoline-2,3-dione.

ABSTRACT: The title compound, C10H8BrNO2, crystallizes with two independent molcules (A and B) in the asymmetric unit. In each mol-ecule, the indoline ring system is almost planar, with the largest deviation from the mean plane being 0.016 (2) Å in mol-ecule A and 0.040 (13) Å in mol-ecule B. In each mol-ecule, the ethyl group is nearly perpendicular to the indoline ring system with C-C-N-C torsion angles of -94.8 (3) and 93.0 (3)° in mol-ecules A and B, respectively. In the crystal, the two mol-ecules are inclined to each other, making a dihedral angle of 6.28 (8)°. In the molecular packing, the A and B mol-ecules are linked by C-H⋯O hydrogen bonds, forming -A-B-A-B- chains along [01-1]. Parallel chains are linked via a weak slipped parallel π-π inter-action [inter-centroid distance = 3.6107 (14) Å] and a short Br⋯O contact [3.183 (2) Å], forming a three-dimensional structure.

1-Ethyl-5-iodo-indoline-2,3-dione.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C10H8INO2, which differ in the degree of planarity. The iodo-indoline-2,3-dione skeleton of mol-ecule 1 is essentially planar [mean deviation = 0.003 (2) Å for the nine non-H atoms of the indoline core, with a maximum deviation of 0.033 (1) Å for the I atom]. The I atom and O atom in the 3-position of mol-ecule 2 deviate by 0.195 (1) and 0.120 (2) Å, respectively, from the least-squares plane through the nine non-H atoms of the indoline core. Mol-ecules 1 and 2 are roughly coplanar, the mean planes through their cores making a dihedral angle of 6.84 (1)°. This coplanarity results in a layer-like structure parallel to (6,11,17) in the crystal, the distance between adjacent least-squares planes through the cores of mol-ecules 1 and 2 being 3.37 (1) Å. In such a layer, mol-ecules 1 and 2 are linked by C-H⋯O hydrogen bonds, forming chains along [11-1]. The chains are further coupled to construct a kind of double-chain structure via I⋯O inter-actions [3.270 (2) Å].

Crystal and geometry-optimized structure, and Hirshfeld surface analysis of 1-(2-bromo-eth-yl)indoline-2,3-dione.

Project description:In the title compound, C10H8BrNO2, the isatin (1H-indole-2,3-dione) moiety is nearly planar (r.m.s. deviation = 0.026 Å). In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming layers parallel to the ab plane, and enclosing R44(24) loops. There are a low percentage (19.3%) of inter-molecular H⋯H contacts in the structure, as estimated by the analysis of Hirshfeld surfaces. This could be due to the presence of the Br atom, present in the bromo-ethyl-ene group, which makes ca 18.7% Br⋯H contacts.

Project description:There are two mol-ecules in the asymmetric unit of the title compound, C(8)H(4)ClNO(2). In the crystal, they are linked by N-H?O hydrogen bonds, generating centrosymmetric, tetra-meric assemblies. A C-H?O inter-action also occurs.

Project description:In the title N-alkyl isatin, C(18)H(25)NO(2), the isatin moiety is almost planar (r.m.s. deviation = 0.03?Å). C-C-C-C torsion angles of the decyl substituent indicate an all-antiperiplanar conformation.

Crystal structure, Hirshfeld surface analysis and DFT studies of 5-bromo-1-{2-[2-(2-chloro-eth-oxy)eth-oxy]eth-yl}indoline-2,3-dione.

Project description:The title compound, C14H15BrClNO4, consists of a 5-bromo-indoline-2,3-dione unit linked to a 1-{2-[2-(2-chloro-eth-oxy)eth-oxy]eth-yl} moiety. In the crystal, a series of C-H?O hydrogen bonds link the molecules to form a supramolecular three-dimensional structure, enclosing R 2 2(8), R 2 2(12), R 2 2(18) and R 2 2(22) ring motifs. ?-? contacts between the five-membered dione rings may further stabilize the structure, with a centroid-centroid distance of 3.899?(2)?Å. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H?H (28.1%), H?O/O?H (23.5%), H?Br/Br?H (13.8%), H?Cl/Cl?H (13.0%) and H?C/C?H (10.2%) inter-actions. Hydrogen bonding and van der Waals inter-actions are the dominant inter-actions in the crystal packing. Density functional theory (DFT) optimized structures at the B3LYP/6-311G(d,p) level are compared with the experimentally determined mol-ecular structure in the solid state. The HOMO-LUMO behaviour was elucidated to determine the energy gap. The chloro-eth-oxy-ethoxyethyl side chain atoms are disordered over two sets of sites with an occupancy ratio of 0.665?(8):0.335?(6).

1-Do-decyl-indoline-2,3-dione.

Project description:The structure of the title compound, C20H29NO2, is isotypic to that of its homologue 1-octylindoline-2,3-dione.

All C atoms of the dodecyl group are in an anti-periplanar arrangement. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming a three-dimensional network.
