Project description:In the title compound, C18H22N2O4S2, the 2H-chromene ring system is essentially planar (r.m.s. deviation = 0.012?Å).

Project description:In the title compound, C17H19NO3S2, the maximum deviation of atoms in the 2H-chromene ring system is 0.0097?(14)?Å and the piperidine ring adopts a chair conformation.

3'-[Hy-droxy(4-oxo-4H-chromen-3-yl)meth-yl]-2-oxospiro-[indoline-3,2'-pyrrolidine]-3'-carbonitrile.

Project description:In the title compound, C(23)H(19)N(3)O(4), the pyran ring adopts a half-chair conformation, while the pyrrolidine (with a C atom as the flap atom) and the five-membered ring in the indoline (with a C atom as the flap atom) ring system adopt slight envelope conformations. The pyrrolidine ring makes dihedral angles of 83.3?(1) and 60.4?(1)° with the mean plane through all non-H atoms of the indoline and chromene ring systems, respectively. In the crystal, mol-ecules are connected by two unique N-H?O and O-H?O hydrogen-bonding inter-actions, which form centrosymmetric patterns described by graph-set motifs R(2) (2)(18) and R(2) (2)(14). These two motifs combine to form a hydrogen-bonded chain which propagates in the a-axis direction. The crystal structure is also stablized by C-H?O inter-actions and by aromatic ?-? stacking inter-actions between the pyran and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.755?(1)?Å and slippage = 1.371?(2)?Å].

4-Hy-droxy-3-[(4-hy-droxy-2-oxo-2H-3-chromen-yl)(3-thien-yl)meth-yl]-2H-chromen-2-one.

Project description:The whole mol-ecule of the title compound, C(23)H(14)O(6)S, is disordered over two sets of sites with refined occupancies of 0.8733?(12):0.1267?(12). The dihedral angle between the mean planes through the chromene ring systems is 56.31?(5) and 55.2?(3)° for the major and minor components, respectively. In both components, a pair of intra-molecular O-H?O inter-actions generate rings of S(8) graph-set motif.

The structure is further stabilized by ?-? inter-actions with centroid-centroid distances of 3.594?(2) and 3.608?(5)?Å.
