4′-Formyl­benzo-15-crown-5

IN THE TITLE COMPOUND (SYSTEMATIC NAME 17-formyl-2,5,8,11,14-penta-oxabicyclo-[13.4.0]nona-deca-15,17,19-triene), C(15)H(20)O(6), the 15-crown-5 ring adopts a twisted conformation. The formyl group is coplanar with the benzene ring. The crystal packing is stabilized by C-H⋯O inter-actions involving the C=O group and ether O atoms as acceptors and methyl-ene CH groups as donors.

Aqua­chloridodimethyl­phenyltin(IV)–15-crown-5 (2/1)

The Sn(IV) atom in the title compound, 2[Sn(CH(3))(2)(C(6)H(5))Cl(H(2)O)]·C(10)H(20)O(5), exists in a trans-C(3)SnClO trigonal bipyramidal geometry in which the organo substituents occupy the equatorial sites. The coordinated water mol-ecule forms two hydrogen bonds to the 15-crown-5 mol-ecule, which is disordered about a center of inversion.

More examples of the 15-crown-5...H2O-M-OH2...15-crown-5 motif, M = Al3+, Cr3+ and Pd2+.

Five structures of co-crystals grown from aqueous solutions equimolar in 15-crown-5 (or 15C5) and [M(H(2)O)(6)](NO(3))(n), M = Al(3+), Cr(3+) and Pd(2+), are reported. The hydrogen-bonding patterns in all are similar: metal complexes including the fragment trans-H(2)O-M-OH(2) alternate with 15C5 molecules, to which they are hydrogen bonded, to form stacks. A literature survey shows that this hy...

Spectroscopic Studies on Charge-Transfer Complexation of Iodine with Dibenzo-15-crown-5 and Benzo-12-crown-4 in Chloroform, Dichloromethane and 1,2-Dichloroethane

The formation of charge-transfer complexation between dibenzo-15-crown-5 (DB15C5) and benzo-12-crown-4 (B12C4) (Donor) and iodine is investigated spectrophotometrically in three chlorinated solvents,chloroform, dichloromethane (DCM) and 1,2-dichloroethane (DCE) solution at 25°C. The change in polarityof the solvent also doesn’t affect the stoichiometry of the complexes. Values of formation cons...

Bis(benzo-15-crown-5-κ5 O)strontium bis­(triiodide)

The title compound, [Sr(C(14)H(20)O(5))(2)](I(3))(2), obtained by slow evaporation of an ethanol/dichloro-methane solution (1:1) of SrCl(2), benzo-15-crown-5 and I(2), is built of sandwich-like [Sr(benzo-15-crown-5)(2)](2+) cations and isolated linear I(3) (-) anions which are arranged in alternating layers parallel to (010). The triiodide anions are located in general positions, whereas the ca...
