Abstract A novel calix[4]arene derivative, 26,28-bis(cyanomethoxy)-25,27-dihydroxycalix[4]arene (1), was synthesized and its crystal structure has been determined. The crystals, obtained by recrystallization from acetone, are triclinic, space group P-1, with a=10.1160(17) A , b=11.996(2) A , c=13.148(2) A , and α=63.331(3)°, β=74.392(4)°, γ=85.077(4)°. As compared with a similar compound, 5,11,17,
