    摘要: Cobalt complexes of Co(3Cn)2(MeOH)4, derived from 3,4,5-trialkyloxybenzoate ligand (noted as 3Cn) with n = 10, 12, 14 and 16, were synthesized and characterized. The crystal of Co(1C12)2(MeOH)4 were determined by means of x-ray single crystal analysis. It crystallizes in the monoclinic P21/c space group with a = 24.3271(19) Å, b = 14.0058(11) Å, c = 6.4612(4) Å, α = γ = 90o, β = 94.368(4)o, and Z = 2. The phase texture and mesogenic properties were detected by polarized optical microscopic and powder x-ray diffraction technique. It was found that these compounds display the cubic phases. Differential scanning calorimetric data indicated that these compounds were nearly room temperature liquid crystalline and with a very wide mesogenic phase range.
