5-Chloro-spiro-[indoline-3,7'-6H,7H,8H-pyrano[3,2-c:5,6-c']di[1]benzopyran]-2,6',8'-trione.

ABSTRACT: The asymmetric unit of the title compound, C(26)H(12)ClNO(6), consists of two independent mol-ecules. The central pyran rings and both the 1-benzopyran ring systems are nearly planar in both mol-ecules [r.m.s. deviations of pyan rings = 0.0264?(1) and 0.0326?(1)?Å for molecules A and B, respectively; r.m.s. deviations of benzopyran rings = 0.0439?(1) and 0.0105?(1) for molecule A, 0.0146?(1) and 0.0262?(1)?Å for molecule B]. In the crystal, the molecules are linked by C-H?O, N-H?O and C-H?? inter-actions.

The asymmetric unit of the title compound, C(26)H(12)ClNO(6), consists of two independent mol-ecules. The central pyran rings and both the 1-benzopyran ring systems are nearly planar in both mol-ecules [r.m.s. deviations of pyan rings = 0.0264 (1) and 0.0326 (1) Å for molecules A and B, respectively; r.m.s. deviations of benzopyran rings = 0.0439 (1) and 0.0105 (1) for molecule A, 0.0146 (1) and 0.0262 (1) Å for molecule B].

5-Methyl-spiro-[indoline-3,7'-[6H,7H,8H]pyrano[3,2-c:5,6-c']di[1]benzopyran]-2,6',8'-trione chloroform hemisolvate.

Project description:In the title compound, C(27)H(15)NO(6)·0.5CHCl(3), the central pyran ring and both the benzopyran systems are planar, with the dihedral angle between the outer rings being 3.24?(6)°. The indolin-2-one system is in a perpendicular configuration with respect to the pyran ring [dihedral angle = 87.58?(2)°]. Supra-molecular layers in the ac plane are formed in the crystal structure whereby inversion-related mol-ecules are connected by N-H?O hydrogen bonds. These are further linked by C-H?O inter-actions, forming a supra-molecular layer in the ac plane. Disordered CHCl(3) solvent in the structure was modelled with the SQUEEZE routine in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155].

5,6-Dimethyl-1,2,9,10-tetra-hydro-pyrano[3,2-f]chromene-3,8-dione.

Project description:The title mol-ecule, C(14)H(14)O(4), lies on a twofold rotation axis that bis-ects the central benzene ring, with only one half-mol-ecule in the asymmetric unit. The pyran-one systems adopt distorted twist- boat conformations, with the two methyl-ene C atoms displaced by 0.537?(1) and 0.163?(2)?Å from the best-fit plane through the remaining five C and O atoms (r.m.s. deviation = 0.073?Å). In the crystal, bifurcated C-H?(O,O) hydrogen bonds link pairs of adjacent mol-ecules in an obverse fashion, stacking mol-ecules along c. These contacts are further stabilized by very weak ?-? inter-actions between adjacent benzene rings with centroid-centroid distances of 4.1951?(4)?Å. Additional C-H?O contacts link these stacks, giving a three-dimensional network.
