title: Di-tert-Butyl 2,2'-[2,2'-methyl-enebis(naphthalene-2,1-diyldi-oxy)]diacetate.
abstract: In the title compound, C(33)H(36)O(6), two naphthalene ring systems are connected through a methyl-ene linkage [C-C-C = 114.9 (2)°]; the ring systems are aligned at an angle of 76.5 (1)°. Of the two -O-CH(2)-C(=O)-C(CH(3))(3) substituents, one adopts an extended conformation whereas the other is U-shaped. In the crystal, mol-ecules are linked via weak C-H⋯O hydrogen bonding, forming supra-molecular chains running along the c axis.
