9,9-Bis(ethoxy­carbonyl­ethyl)-9H-fluorene

In the title compound [systematic name: diethyl 3,3′-(9H-fluorene-9,9-di­yl)dipropionate], C23H26O4, the fluorene ring system is planar. The ethoxy­carbonyl­ethyl groups display extended conformations and are nearly perpendicular to the fluorene plane. A weak inter­molecular C—H⋯O inter­action occurs in the crystal structure.
