E. Campillos et al., MESOMORPHIC (ETA(6)-ARENE)TRICARBONYLCHROMIUM COMPLEXES, Journal of the Chemical Society. Dalton transactions, (12), 1996, pp. 2533-2536
The first family of (eta(6)-arene)tricarbonylchromium complexes contai
ning thermotropic liquid crystals has been prepared and the mesomorphi
c properties studied. Enantiotropic smectic C and-nematic phases were
observed. Comparison of their X-ray diffraction characteristics and li
quid-crystalline behaviour with those of the metal-free analogues emph
asized the influence of the organometallic unit on the mesophase featu
res.
