The title complex is asymmetric in the crystal due to the spatial orientation of the NCS function. The space group has been determined to be P21 with a = 9.496(3), b = 8.736(3), c = 9.676(3) Å, β = 117.859(5)°, and Z = 2. The solid state 13C NMR spectrum is consistent with the lack of symmetry in the crystal and there is little evidence for large amplitude motion in the macrocycle as determined from the dipolar dephased spectrum.Key words: macrocyclic crown ether, lithium complex.

Benzo-9-crown-3 ether trimerizes in the presence of FeCl3 and aqueous H2SO4 to produce tris(9-crown-3)triphenylene in 25.4% yield. This compound crystallizes in the monoclinic P21/c space group: a = 13.759(2) Å, b = 13.318(2) Å, c = 13.399(2) Å, β = 96.883(2)°, with Z = 4. The three 9-crown-3 ether units of the trimer possess different geometries and there is substantial deviation from coplanarity in the three aromatic rings. 13C NMR chemical shifts in the solid state are consistent with this lack of symmetry and are discussed in terms of the X-ray crystal-structure data.Key words: crown ether, trimerization, stereochemistry.

Fluorescent Material

A novel bi-Schiff-base Zn (II) complex, 1-acetyl-2-naphthol-4, 4’-diaminodiphenylmethane Zn (II), has been synthesized. The luminescent characterizations of the Zn (II) complex material have been studied in solid state and in organic solvents, and the effect of Mg (II) ion on the fluorescence of Zn (II) complex has also been investigated in organic solvents. The results show that the Zn (II) complex material emits weak green fluorescence at 536 nm in solid, emits strong blue fluorescence 451 nm in DMSO. However, there do have luminescent emissions in methanol and in ethanol duo to the influence of overtones.
