8-[(Hydrazinyl-idene)meth-yl]-4-methyl-2-oxo-2H-chromen-7-yl 4-methyl-benzene-sulfonate.

ABSTRACT: In the title compound, C(18)H(16)N(2)O(5)S, the coumarin ring system is nearly planar, with a maximum out-of-plane deviation of 0.078?(1)?Å (r.m.s. deviation = 0.046?Å). The dihedral angle between the coumarin ring system and the toluene ring (r.m.s. deviation = 0.004?Å) is 2.77?(1)°. The crystal packing is stabilized by C-H?O and N-H?O inter-molecular hydrogen bonds generating C(8), C(9) and C(11) chains and R(2) (2)(14), R(2) (2)(23) and R(4) (3)(13) ring graph sets.

In the title compound, C(18)H(16)N(2)O(5)S, the coumarin ring system is nearly planar, with a maximum out-of-plane deviation of 0.078 (1) Å (r.m.s. deviation = 0.046 Å). The dihedral angle between the coumarin ring system and the toluene ring (r.m.s. deviation = 0.004 Å) is 2.77 (1)°. The crystal packing is stabilized by C-H⋯O and N-H⋯O inter-molecular hydrogen bonds generating C(8), C(9) and C(11) chains and R(2) (2)(14), R(2) (2)(23) and R(4) (3)(13) ring graph sets. ...[more]

2-Oxo-2H-chromen-4-yl 4-methyl-benzoate.

Project description:The asymmetric unit of the title compound, C17H12O4, consists of two independent mol-ecules. The chromen-2-one ring and the 4-methyl-benzoate side chain are inclined to one another at a dihedral angle of 64.79?(10)° in one mol-ecule and 88.3?(1)° in the other. In the crystal, mol-ecules form R 2 (2)(8) centrosymmetric dimers via C-H?O hydrogen bonds. These dimers are stacked by C-H?O hydrogen bonds, resulting in R 2 (2)(18) and R 3 (2)(16) ring motifs. ?-? stacking inter-actions between two parallel chromen-2-one rings, with centroid-centroid distances of 3.743?(1) and 3.771?(1)?Å, are also present.

Project description:The title mol-ecular salt, C9H12N3O2S+·HSO4 -, was obtained through the protonation of the azomethine N atom in a sulfuric acid medium.

In the crystal, a three-dimensional network is established through O-H?O and N-H?O hydrogen bonds. A weak intermolecular C-H?O hydrogen bond is also observed. The hydrogen sulfate anion exhibits disorder over two sets of sites and was modelled with refined occupancies of 0.501?(6) and 0.499?(6).
