چکیده
In the cation of the title salt, C(12)H(14)N(3)O(+)·C(24)H(20)B(-), the dihedral angle between the quinoline ring and the mean plane of the urea fragment is 61.51 (5)°. In the crystal, the cations inter-act through weak C-H⋯O hydrogen bonding, forming a zigzag chain along the c-axis direction; the cations and anions are involved in weak inter-molecular C-H⋯π and N-H⋯π inter-actions as donors and acceptors, respectively.

Crystal structure of bis(quinolin-1-ium) tetrachloridoferrate(III) chloride
The asymmetric unit of the title hybrid compound, (C9H8N)[FeCl4]Cl, comprises a tetra-hedral tetra-chlorido-ferrate(III) anion, [FeCl4](-), a Cl(-) anion and two quinolinium cations. There are N-H⋯Cl hydrogen-bonding inter-actions between the protonated N atoms of the quinolinium cations and the chloride anion, which together with π-π stacking between adjacent quinolinium rings [centroid-to-cen...
متن کاملA coumarin-quinolinium-based fluorescent probe for ratiometric sensing of sulfite in living cells.
Based on a novel coumarin-quinolinium platform, probe 2 was rationally designed and synthesized as a novel ratiometric fluorescent sensor for sulfite anions. The probe exhibited a wide dynamic concentration range for sulfite anions in a PBS buffer (containing 1 mg mL(-1) BSA). More importantly, the probe was suitable for ratiometric fluorescence imaging in living cells with high sensitivity, fa...

A reaction of [PdCl2(cod)] (cod = 1,5-cyclooctadiene) and an E/Z mixture of quinoline-2-carbaldehyde (pyridine-2-carbonyl)hydrazone (HL) gave two kinds of Pd(II) mononuclear complexes, [PdCl(Z-L-κ(3)N,N',N'')] (1) and [PdCl2(E-HL'-κ(2)N,N')] (2), where L(-) is the deprotonated hydrazonate anion and HL' is the quinolinium-hydrazonate zwitterionic form of HL. Complex 2 is gradually converted to 1...

Quinolinium cations and quinolinium betaines were investigated in the representative solvents water and acetonitrile at room temperature using stationary and time-resolved fluorescence spectroscopy (Single-Photon-Counting-method). Experimental results reveal that sulfoalkyland carboxyalkyl-quinolinium compounds display a strikingly different behavior in the two solvents. Furthermore, the fluore...
متن کاملcatena-Poly[1-[(2-fluorobenzylidene)amino]quinolinium [plumbate(II)-tri-μ-iodido]]
The title complex, {(C(16)H(12)FN(2))[PbI(3)]}(n), consists of 1-[(2-fluoro-benzyl-idene)amino]-quinolinium cations and a polymeric PbI(3) (-) anion formed by face-sharing PbI(6) octa-hedra. These octa-hedra form straight and regular infinite chains along the b axis. In the asymmetric unit, one cation and one anionic [PbI(3)](-) fragment are observed in general positions. Polymeric chains are p...
