The crystal structure of 25,27-dihydroxy-26,28-bis(diethoxyphosphoryloxy)-tert-butylcalix[4]arene (1) (hexane solvate, 1:1) was determined by x-ray crystallography. The crystal data are P2 1 /n, a = 12.652(1) A Λ, b = 12.564(2) A Λ, c = 18.781(4) A Λ, b = 105.56(1)Β°, V = 2876.0(8) A Λ3, Z = 2. In th
