In the title compound, C(31)H(28)O(4), the asymmetric unit contains two crystallographically independent mol­ecules. In these two mol­ecules, the four dihedral angles between each pair of phenyl rings on the same C atoms are 75.4 (1), 83.0 (1), 85.0 (1) and 80.4 (2)°. All of the nonplanar six-member...

description In the title compound, C(31)H(28)O(4), the asymmetric unit contains two crystallographically independent mol­ecules. In these two mol­ecules, the four dihedral angles between each pair of phenyl rings on the same C atoms are 75.4 (1), 83.0 (1), 85.0 (1) and 80.4 (2)°. All of the nonplanar six-membered heterocycles adopt chair conformations. Inter­molecular C—H⋯π and weak C—H⋯O inter­actions link the mol­ecules and are effective in the stabilization of the crystal structure.
