Crystal structure and fluorescence behavior of N,N'-bis (1-naphthylmethyl)-diazonia-18-crown-6 diisothiocyanate.
N,N'-bis (1-naphthylmethyl)-diaza-18-crown-6 (1) showed weak emissions, suggesting that photoinduced electron transfer (PET) from the amine group to the excited naphthalene occurs. The PET fluoroionophore (1) was found to display unique photophysical properties in the presence of a guest cation. Single crystals of the HNCS salt of 1 were grown from 1 and NH(4)SCN. The crystal structure of the H...
متن کاملBis(hydroxyammonium) hexachloridoplatinate(IV)–18-crown-6 (1/2)
In the title complex, (NH3OH)2[PtCl6]·2C12H24O6, the Pt(IV) atom is coordinated by six chloride anions in a slightly distorted octa-hedral geometry. The Pt-Cl bond lengths are comparable to those reported for other hexa-chlorido-platinate(IV) species. The hy-droxy-ammonium groups act as linkers between the [PtCl6](2-) anion and the crown ether mol-ecules. The anion is linked to two hy-droxy-amm...
متن کاملBenzylaminium perchlorate–18-crown-6 (1/1)
In the title compound, C(7)H(10)N(+)·ClO(4) (-)·C(20)H(24)O(6), the proton-ated benzyl-amine cation forms a rotator-stator complex with the 18-crown-6 (1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne) mol-ecule via N-H⋯O hydrogen bonds. The cations are associated via weak C-H⋯π inter-actions, forming chains parallel to [011], while the perclorate anions are located between these chains.
متن کاملAmmonium hexafluoridophosphate–18-crown-6 (1/1)
In the crystal structure of the title compound, NH(4) (+)·PF(6) (-)·C(12)H(24)O(6), the cation is situated in the 18-crown-6 ring, forming a supra-molecular rotator-stator-like structure held by N-H⋯O hydrogen bonds. The six O atoms of the crown ether lie approximately in a plane [mean deviation 0.2129 (3) Å]; the N atom is displaced by 0.864 (3)Å from the centroid of the 18-crown-6 ring. The s...

In the title compound, [Fe(III)(C48H36N4O2)(H2O)2][K(C12H24O6)(H2O)2](SO3CF3)2·2C12H24O6, the Fe(III) atom is situated on an inversion centre and is octa-hedrally coordin-ated by four pyrrole N atoms of the deprotenated 5,10,15,20-tetra-kis-(4-meth-oxy-phen-yl)porphyrinate ligand and two water mol-ecules. The average equatorial Fe-N(pyrrole) bond length [2.043 (6) Å] is consistent with a high-s...
