EnglishThe sysnthesis and characterization of two series of chiral mononuclear palladium(II) azocompounds, (L(N)(n))Pd(acac)], prepared by bridge splitting reactions or the dinuclear parents {Pd[L(N)(n)]mu-Cl)}2 with thallium acetylacetonate are reported. All the complexes, bearing a stereogenic centre in the alkoxy lateral chain (R*O = R-(-)-2-octyl; S-(-)-beta-citronellyl), are mesomorphic. Their thermotropic behaviour has been investigated by differential scanning calorimetry, optical microscopy and X-ray diffraction. Worthy of note, the clearing temperatures of all the compounds are below 70-degrees-C. The relationship between ligands, mu-Cl dimers and mononuclear acetylacetonate complexes is discussed.
