In the title compound, C(17)H(15)BrO(2)S, the 4-bromo-phenyl ring makes a dihedral angle of 87.12 (6)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions.

In the title compound, C(18)H(19)NO(2), the five-membered ring of the indane fragment adopts an envelope conformation, with the unsubstituted C atom, acting as the flap atom, deviating by 0.412 (3) Å from the plane through the remaining four atoms. The dihedral angle between the nitro-phenyl ring and the indane benzene ring is 72.5 (1)°. The distances from the two O atoms to the plane of the ad...

In the title compound, C(18)H(18)O(3)S, the 4-methyl-phenyl ring makes a dihedral angle of 86.35 (3)° with the mean plane [mean deviation = 0.006 (1) Å] of the benzofuran fragment. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π inter-actions. The crystal structure also exhibits weak π-π inter-actions between the furan and benzene rings of neighbouring benzofuran systems [centroid...

The compound 2-((1,3-dimethyl-1H-pyrazol-5-yl)(methyl)carbamoyl)benzene-diazonium hydrogen sulfate (10) was reacted with copper sulfate and sodium chloride, in the presence of ascorbic acid as reducing agent, to afford a mixture of the chlorinated epimers 4'-chloro-2,2',5'-trimethyl-2',4'-dihydrospiro[isoindoline-1,3'-pyrazol]-3-one (18) and (19), the epimers 4'-hydroxy-2,2',5'-trimethyl-2',4'-...

The Sn(IV) atom in the title salt, [N(CH(3))(3)(C(6)H(5))](2)[SnBr(4)(C(6)H(4)Cl)(2)], exists in a distorted all-trans SnC(2)Br(4) octa-hedral geometry. The Sn(IV) atom lies on a center of inversion. Weak inter-molecular C-H⋯Br hydrogen bonding is observed between trimethyl-phenyl-ammonium cations and the Sn complex anion in the crystal structure.

The 1,3-dioxine ring in the title compound, C(13)H(13)FO(3), is in a half-boat conformation with the methyl-bonded C atom 0.612 (2) Å out of the plane defined by the remaining five atoms.

A new styryl dye were prepared, 2-[2-(4-dipropylamino-phenyl)-vinyl]-1,3,3-trimethyl-3H-indolium chloride (DPPTVI) chloride. Its infrared and Raman were measured. Quantum chemical calculations were computed for both the isolated and the solute cation. Optimized geometry, atomic net charges were calculated. The calculated vibrational frequencies were scaled to the experimental ones. Only 12 scal...

In the title compound, C(12)H(14)N(2)S, the dihedral angle between the 1,3,5-trimethyl-benzene and 1,3-thia-zol-2-amine groups is 73.15 (4)°. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds generate R(2) (2)(8) loops.

The title compound, C(14)H(24)NO(+)·Cl(-), crystallizes with four independent mol-ecules in the asymmetric unit. It was isolated from plant Pachysandra terminalis Siebold & Zucc. The six-membered ring has a conformation close to an envelope. In the crystal, N-H⋯Cl hydrogen-bonding inter-actions exist between secondary ammonium groups and free chloride anions, resulting in a one-dimensional supr...
