In the title compound, C17H12O5, the dihedral angle between the planes of the coumarin ring system (r.m.s. deviation = 0.015 Å) and the benzene ring is 48.04 (10)°. The central CO2 group subtends a dihedral angle of 27.15 (11)° with the coumarin ring system and 74.86 (13)° with the benzene ring. In the crystal, mol-ecules are linked by C-H⋯O inter-actions,(More)
The complete mol-ecule of the title compound, C17H16O6, is generated by crystallographic twofold symmetry, with the central methyl-ene C atom lying on the rotation axis. The carbonyl O atom is disordered over two adjacent positions in a 0.63 (3):0.37 (3) ratio and the dihedral angle between the benzene rings in the two halves of the mol-ecule is 79.31(More)
In the title chiral mol-ecular salt, C4H12NO3S(+)·Cl(-), the cation is protonated at the N atom, producing [RNH3](+), where R is CH3SO2OCH2C(H)CH3. The N atom in the cation is sp (3)-hybridized. In the crystal, cations and anions are connected by strong N-H⋯Cl hydrogen bonds to generate edge-shared 12-membered rings of the form {⋯Cl⋯HNH}3. This pattern of(More)
The tetra-hydro-pyridine ring of the quinoline system in the title compound, C14H13ClN2O2S, adopts a half-chair conformation with the bond-angle sum at the N atom being 350.0°. The dihedral angle between the least-squares planes of the two aromatic rings is 50.13 (11)°. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R 2(More)
In the title compound, C16H17NO2S, the heterocyclic ring adopts a half-chair conformation and the bond-angle sum at the N atom is 354.6°. The dihedral angle between the planes of the aromatic rings is 74.15 (10)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, generating C(8) and C(4) chains propagating along [100] and [010],(More)
In the title mol-ecular salt, C10H15ClNS(+)·Cl(-), the cation is [R'R"NH2](+), where R' is 2-MeS-C6H4CH2- and R" is -CH2CH2Cl, and the anion is Cl(-). In the cation, the N atom is protonated with sp (3)-hybridization and with a tetra-hedral geometry. In the crystal, the anions are connected to the cations through two pairs of N-H⋯Cl hydrogen bonds,(More)
In the title compound, C16H9BrO4, the coumarin ring system is approximately planar, with an r.m.s deviation of the ten fitted non-H atoms of 0.031 Å, and forms a dihedral angle of 25.85 (10)° with the bromo-benzene ring. The carbonyl atoms are syn. In the crystal, mol-ecules are connected along [001] via C-H⋯O inter-actions, forming C(6) chains.(More)
In the title compound, C7H4F2O3, an intra-molecular O-H⋯O hydrogen bond is observed. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R 2 (2)(8) ring motifs. These dimers are linked by C-H⋯O and C-H⋯F hydrogen bonds, forming sheets lying parallel to (30-1). The sheets are linked by aromatic π-π stacking inter-actions(More)
In the title compound, C18H18N2O4S, the dihedral angle between the aromatic rings is 33.71 (9)° and an intra-molecular C-H⋯O hydrogen bond closes an S(6) ring. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯N hydrogen bonds to generate a three-dimensional network. A very weak aromatic π-π stacking inter-ction is also observed [centroid-centroid(More)
