Crystal structure of 9,9-di-ethyl-9H-fluorene-2,4,7-tricarbaldehyde.

ABSTRACT: The title compound, C₂₀H₁₈O₃, crystallizes in the space group P2₁/c with one mol-ecule in the asymmetric unit of the cell. The fluorene skeleton is nearly planar and the crystal structure is composed of mol-ecular layers extending parallel to the (302) plane. Within a layer, one formyl oxygen atom participates in the formation of a C_arene-H⋯O bond, which is responsible for the formation of an inversion symmetric supra-molecular motif of graph set R ₂ ²(10). A second oxygen atom is involved in an intra-molecular C_arene-H⋯O hydrogen bond and is further connected with a formyl hydrogen atom of an adjacent mol-ecule. A Hirshfeld surface analysis indicated that the most important contrib
