Extensive strong N-H⋯O and weak C-H⋯O inter-molecular hydrogen-bonding inter-actions occur between dimethyl-formamide (DMF), the crystallizing solvent, and the various heterocyclic groups within the compound, as well as additional weak C-H⋯O inter-actions between the heterocyclic groups themselves. The carboxyl group of the DMF solvent mol-ecule forms a trifurcated (four-center) acceptor hydrogen-bond inter-action with the carboxamide, furan and 6-methyl-4-oxo-4H-chromen-3-yl groups.
