9-(Methylsulfanyl)acridinium trifluoromethanesulfonate
In the crystal structure of the title compound, C(14)H(12)NS(+)·CF(3)SO(3) (-), N-H⋯O hydrogen bonds link cations and anions into ion pairs. Inversely oriented ion pairs form stacks through multidirectional π-π inter-actions among the acridine units. The crystal structure features a network of C-H⋯O inter-actions among stacks and also long-range electrostatic inter-actions among ions. In the pa...
متن کاملPolarized x-ray-absorption spectra of TiS2, TiSe2, and TiTe2
We studied the anisotropy of the unoccupied electron states of three titanium dichalcogenides by means of polarized x-ray-absorption spectroscopy. The experimental spectra of TiS2, TiSe2, and TiTe2 at the Ti K edge and of TiTe2 at the Te L1 edge were compared with the results of real-space multiple-scattering calculations. The local angular momentum projections of the densities of states at the...
متن کامل9-Phenyl-10H-acridinium trifluoromethanesulfonate
In the crystal structure of the title compound, C(19)H(14)N(+)·CF(3)SO(3) (-), the cations are linked to each other by very weak C-H⋯π inter-actions, while the cations and anions are connected by N-H⋯O, C-H⋯O and S-O⋯π inter-actions. The acridine ring system and the phenyl ring are oriented at an angle of 80.1 (1)° with respect to each other. The mean planes of adjacent acridine units are eithe...
متن کامل10-Methyl-9-(2-nitrophenoxycarbonyl)acridinium trifluoromethanesulfonate
The crystal structure of the title compound, C(21)H(15)N(2)O(4) (+)·CF(3)O(3)S(-), is stabilized by C-H⋯O and C-H⋯F hydrogen bonds, by C-F⋯π, N-O⋯π and S-O⋯π inter-actions, and by O⋯O [2.70 (4) Å] and O⋯F [2.85 (1) or 2.92 (1) Å] contacts; π-π interactions are also present. In the packing of the mol-ecules, acridine units are either parallel or inclined at an angle of 12.5 (1)°. The nitrophenox...
متن کاملPolarized x-ray absorption spectra of CuGeO3 at the Cu and Ge K edges
Polarized x-ray absorption near edge structure ~XANES! spectra at both the Cu and Ge K edges of CuGeO3 are measured and calculated relying on the real-space multiple-scattering formalism within a one-electron approach. The polarization components are resolved not only in the unit cell coordinate system («i a , «i b , «i c) but also in a local frame attached to the nearest neighborhood of the ph...
