Abstract: The lower-rim partially substituted sulfonylcalix[4]arenes, 5,11,17,23-tetra-tert-butyl-25,26,27-tris[(ethoxycarbonyl)methoxy]-2,8,14,20-tetrasulfonylcalix[4] arene(L1) and 5,11,17,23-tetra-tert-butyl-25,26,27-tris(oxyacetic acid)-2,8,14,20-tetrasulfonyl calix[4]arene(L2), and the complexes of L2 were synthesized and characterized. The crystal structure of L1 was determined by X-ray diffraction. The results show that the composition of it is C52H65KO18S4·0.5H2O. It belongs to triclinic crystal system, P1 space group, with a=1.2607(6) nm, b=1.5820(8) nm, c=1.648 0(8) nm, α=83.720(8)°, β=69.327(8)°, γ=79.342(9)°, Z=2, V=3.019(3) nm3, Dc=1.270 g·cm-3, F(000)=121.8, μ=0.293 mm-1, R1=0.0937, wR2=0.2580. The calix[4]arene adopts a partial cone conformation.
