Molecular organization and molecular order of polymesomorphic thiophene based mesogens were investigated by variable temperature powder X-ray and high resolution solid state 13C NMR, and the higher order for thiophene in contrast to phenyl rings is attributed to molecular shape.

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.
