Salts of alkaline earth metal cations sequestered in dibenzo-18-crown-6 (Db18c6) and benzo-15crown-5 (B15c5), respectively, with I5−, I7− and I82− as the anions, have been synthesized and their crystal structures determined by single-crystal X-ray diffraction. [Ca(Db18c6)(H2O)3](I5)2(Db18c6)(H2O) (1): monoclinic, P21 (no. 4), a = 1322.1(2), b = 1849.1(2), c(More)
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(More)
A reaction of YI3, dibenzo-24-crown-8 and iodine in ethanol yielded, as a by-product, red single crystals of (I2)@(db24c8). In the triclinic crystal, P-1, a = 485.0(1), b = 1203.7(3), c = 1280.4(2) pm, α = 64.56(2)°, β = 86.82(2)°, γ = 83.89(2)°, V = 671.1(2) × 10pm, Z = 1, R1= 0.0301 for 1965 reflections with I0 > 2σ(I0), iodine molecules with an I–I(More)
