In the crystal, mol­ecules are linked by pairs of C—H?O hydrogen bonds, forming inversion dimers with R 2 2(10) loops. The dimers are linked by further C—H?O hydrogen bonds, forming sheets lying parallel to (001). The mol­ecular packing is further stabilized by C—H?? inter­actions.eninfo:eu-repo/semantics/openAccesscrystal structureArticle
