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.

Project description:In the mol-ecule of the title compound, C(20)H(11)ClN(2)O(3), the pyran ring adopts a flattened-boat conformation. In the crystal structure, inter-molecular N-H?N and N-H?O hydrogen bonds generate edge-fused R(2) (2)(12) and R(2) (2)(14) ring motifs; the hydrogen-bonded motifs are linked to each other, forming a three-dimensional network. A ?-? contact [centroid-to-centroid distance = 3.879?(3)?Å] between the chloro-phenyl rings may further stabilize the structure.

Crystal structure of 4-(6-chloro-4-oxo-4H-chromen-3-yl)-2-methyl-amino-3-nitro-4H,5H-pyrano[3,2-c]chromen-5-one chloro-form monosolvate.

Project description:In the title compound, C23H14Cl4N2O7, the pyran ring has an envelope conformation with the methine C atom as the flap. The chromene rings are almost planar (r.m.s. deviations of 0.027 and 0.018 Å) and their mean planes are inclined to one another by 85.61 (10)°. The mean planes of the pyran ring and the chromene ring fused to it are inclined to one another by 7.41 (13)°. The mol-ecular structure is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R (2) 2(12) ring motif. The dimers are linked by pairs of C-H⋯O hydrogen bonds, enclosing R (2) 2(18) ring motifs, forming chains along [010]. Within the chains there are C-H⋯π inter-actions. The chains are linked via slipped parallel π-π inter-actions, forming a three-dimensional structure [the shortest inter-centroid distance is 3.7229 (19) Å].

Crystal structure of 2-methyl-amino-4-(6-methyl-4-oxo-4H-chromen-3-yl)-3-nitro-pyrano[3,2-c]chromen-5(4H)-one with an unknown solvate.

Project description:In the title compound, C23H16N2O7, the mean planes of the two chromene units (r.m.s. deviations = 0.031 and 0.064 Å) are almost normal to one another with a dihedral angle of 85.59 (6)°. The central six-membered pyran ring has a distorted envelope conformation, with the methine C atom at the flap. There is an intra-molecular N-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(12) ring motif. The dimers are linked by pairs of C-H⋯O hydrogen bonds, enclosing R 2 (2)(6) ring motifs, forming zigzag chains along [001]. The chains are linked by a second pair of C-H⋯O hydrogen bonds, forming slabs parallel to (110). Within the slabs there are C-H⋯π inter-actions present. A region of disordered electron density was treated with the SQUEEZE procedure in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18] following unsuccessful attempts to model it as plausible solvent mol-ecule(s). The given chemical formula and other crystal data do not take into account the unknown solvent mol-ecule(s).

rac-Dimethyl 2-(tert-butyl-amino)-5-oxo-4,5-dihydro-pyrano[3,2-c]chromene-3,4-dicarboxyl-ate.

Project description:The title compound, C(20)H(21)NO(7), is asymmetric with a chiral centre located in the pyran ring and crystallizes as a racemate. The mol-ecular framework is somewhat bent; the coumarin moiety and the pyran ring are inclined by 7.85?(5)°. The mol-ecular structure is characterized by an intra-molecular N-H?O hydrogen bond, which generates an S(6) ring motif, and the crystal packing is stabilized by inter-molecular C-H?O hydrogen bonds. The 3-carboxyl-ate O atom is involved in both of them, having a bifurcated character.

(R,S)-2'-Amino-6'-methyl-2,5',5'-trioxo-6'H-spiro-[indoline-3,4'-pyrano[3,2-c][2,1]benzo-thia-zine]-3'-carbo-nitrile di-methyl-formamide monosolvate.

Project description:The title solvate, C20H14N4O4S·C3H7NO, comprises a stereogenic centre but the centrosymmetric space group causes the presence of the racemate in the crystal. The spiro-joined fragments are almost orthogonal, with a dihedral angle of 86.8?(2)° between the mean planes of the pyrane ring and the dihydroindolone ring system. The atoms of the indolinone bicycle are coplanar, with an r.m.s. deviation of 0.005?Å. In the crystal, pairs of N-H?O hydrogen bonds link the mol-ecules into centrosymmetric dimers which are linked to the di-methyl-formamide solvent mol-ecules by further N-H?O hydrogen bonds. N-H?N hydrogen bonds link neighbouring dimers into [010] chains.

The remaining six-membered ring adopts a twisted conformation. Intra-molecular N-H?O hydrogen bonds occur. In the crystal structure, intera-molecular N-H?O and C-H?O hydrogen bonds link the mol-ecules.
