The title molecule, C18H14N2O5S·C3H7NO, comprises of a carboxamide group bonded to a furan ring and a distorted envelope-shaped 4-oxothiazolidin-3-yl group which is connected to a substituted 6-methyl-4-oxo-4H-chromen-3-yl group. Extensive strong N—H⋯O and weak C—H⋯O intermolecular hydrogen-bonding interactions occur between dimethylformamide (DMF), the crystallizing solvent, and the various heterocyclic groups within the compound, as well as additional weak C—H⋯O interactions between the heterocyclic groups themselves. The carboxyl group of the DMF solvent molecule forms a trifurcated (four-center) acceptor hydrogen-bond interaction with the carboxamide, furan and 6-methyl-4-oxo-4H-chromen-3-yl groups. The dihedral angles between the planar chromone group [maximum deviation = 0.0377 (18)°] and those of the furan and 4-oxothiazolidin-3-yl groups are 89.4 (6) and 78.5 (1)°, respectively.

The title compound was synthesized according to the procedure reported (Zhou et al., 2008). Crystals appropriate for X-ray data collection were obtained by slow evaporation of the DMF solution at 293 K.
All H atoms were initially located in a difference Fourier map. The methyl H atoms were constrained to an ideal geometry, with C—H distances of 0.96 Å, and Uiso(H) = 1.49–1.50 UeqC. Each group was allowed to rotate freely about its C–C bond. All other H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C–H = 0.93–0.98 Å, N–H = 0.77Å and Uiso(H) = 1.19–1.20Ueq(C,N).)

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The tri-substituted chromone (1,4-benzopyrone) pharmacophore is an important structural element in medicinal chemistry, and shows a broad spectrum of pharmacological activities (Maliar et al. (2004), Zhou et al. (2007)). Hence, we were curious to explore the family of biheterocyclic compounds that contain both the thiazolidinone and chromone pharmacophores, with a view to discovering novel lead structures for the development of antifungal agents.
The title molecule is comprised of a carboxamide group bonded to a furan ring and a distorted envelope shaped (Cremer & Pople, 1975) 4-oxothiazolidin-3-yl group (Q(2) = 0.1878 (18) Å, Phi(2) = 188.3 (6)°; for an ideal envelope Phi(2) = k x 36) which is connected to a substituted 6-methyl-4-oxo-4H-chromen-3-yl group (Fig. 1). Extensive strong N2—H2···O6 and weak C16—H16···O6, C20—H20···O6, hydrogen bonding intermolecular interactions occur between dimethylformamide (DMF), the crystallizing solvent, and the various heterocyclic groups within the compound as well as additional weak C—H···O interactions between the heterocyclic groups themselves (Table 1, Fig. 2). The carboxyl group of the DMF solvent forms a trifurcated (4-center) acceptor hydrogen bond interaction with the carboxamide, furan and 6-methyl-4-oxo-4H-chromen-3-yl groups. The dihedral angle between the planar chromone group (max deviation = 0.0377 (18)°) and that of the furan and 4-oxothiazolidin-3-yl groups is 89.4 (6)° and 78.5 (1)°, respectively. Crystal packing is also stabilized by π-π stacking interactions (Cg2—Cg2 = 3.8378 (14) Å; 1 - x, 2 - y, 1 - z; Cg2 is the centroid of the O5/C15—C18 ring).
