Descripción
Sumario:In the title compound, C(40)H(50)O(6), a symmetrical steroid oxalate diester, the dihedral angle between the CO(2) planes of the oxalate linker is 61.5 (5)° and the C—C bond length is 1.513 (6) Å. The steroid B, C and D rings adopt half-chair, chair and envelope conformations, respectively, in both halves of the mol­ecule, which adopts an overall shallow V-shaped conformation. In the crystal, mol­ecules are linked by weak C—H⋯O inter­actions, forming a three-dimensional network.
