Dibenzo-18-crown-6
The asymmetric unit of the title compound, C(20)H(24)O(6), contains two mol-ecules that are identical within standard deviations concerning bond lengths and angles as well as their conformations. In the crystal structure, weak C-H⋯O inter-actions help to consolidate the packing.
متن کاملSn (II) Ion- Selective Membrane Electrode based on Dibenzo-18-Crown-6
We found that dibenzo-18-crown-6 (DB18C6) can be used as an ionophore to make a tin (II)-ionselectivemembrane electrode. The electrode exhibits a near Nernstian response for Sn2+ ions over aconcentration range from 1.0× 10-6 – 1.0× 10-2 M with a slope of 27.5 ± 0.6 mV per concentration decadein an acidic solution (pH=1). The limit of detection was 8.0× 10-7 M. It has a response time of < 20s an...
متن کاملSelective transport of silver ion through a supported liquid membrane using hexathia-18-crown-6 as carrier.
A facile supported liquid membrane (SLM) system for the selective and efficient transport of silver ion is introduced. The SLM used is a thin porous polyvinyldifluoride membrane impregnated with hexathia-18-crown-6 (HT18C6) dissolved in nitrophenyloctyl ether. HT18C6 acts as a specific carrier for the uphill transport of Ag+ ion as its picrate ion paired complex through the SLM. In the presence...
متن کاملHydronium perchlorate–dibenzo-18-crown-6 (1/1): monoclinic polymorph
The asymmetric unit of the title compound, H(3)O(+)·ClO(4) (-)·C(20)H(24)O(6), contains two mol-ecules/ions of each species. Both dibenzo-18-crown-6 mol-ecules have a complexed hydro-nium ion inside their cavity with O-H⋯O and O-H⋯(O,O) links between the two species. The associated perchlorate anions also accept O-H⋯O hydrogen bonds from the hydro-nium ion. Both crown ether mol-ecules are prese...
متن کاملDibenzo-18-crown-6–picric acid–water (1/2/3)
In the crown ether ring of the title compound, C(20)H(24)O(6)·2C(6)H(3)N(3)O(7)·3H(2)O, the O-C(H(2))-C(H(2))-O torsion angles indicate a gauche conformation of the ethyl-eneoxy units, while the C-O-C-C torsion angles indicate planarity of these segments; the dihedral angle between the two benzene rings is 44.53 (13)°. In both picric acid mol-ecules, one of the nitro groups is twisted away from...
