Crystal structure of 2-(11-oxo-10H,11H-indeno[1,2-b]chromen-10-yl)-2,3-dihydro-1H-indene-1,3-dione
In the title mol-ecule, C25H14O4, the fused-ring system consisting of four rings is approximately planar, with a dihedral angle of 9.62 (5)° between the planes of the indene ring system and the benzene ring. The di-hydro-indene-1,3-dione unit makes a dihedral angle of 63.50 (2)° with the mean plane of the fused-ring system. A weak C-H⋯O inter-action organizes the mol-ecules into a helical chain...
متن کاملCrystal structure of 2-(5-bromo-2-hydroxybenzylidene)-2,3-dihydro-1H-indene-1,3-dione
The title mol-ecule, C16H9BrO3, deviates slightly from planarity. The benzene ring makes a dihedral angle of 1.02 (9)° with the plane defined by the five-membered ring of the indandione moiety. The latter exhibits a minute twist indicated by the dihedral angle of 0.47 (9)° between the planes of the five- and six-membered rings. An intra-molecular C-H⋯O hydrogen bond between the attached benzene...

In the title compound, C16H16O4, the five-membered ring of the indene-1,3-dione unit adopts a twist conformation, whereas the seven-membered ring adopts a twist-chair conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, weak C-H⋯O hydrogen bonds and π-π stacking [centroid-to-centroid distance = 3.7373 (8) Å] into a three-dimensional supra-molecular architecture.
متن کاملCrystal structure and luminescent properties of [1-(biphenyl-4-yl)-1H-imidazole-κN 3]dichloridozinc
The mononuclear title compound, [ZnCl2(C15H12N2)2], was synthesized by reaction of zinc chloride and 1-(biphenyl-4-yl)-1H-imidazole (bpi) under hydro-thermal conditions. The Zn(II) atom is tetra-hedrally coordinated by the free imidazole N atoms of two bpi ligands and by two Cl atoms. The bpi ligands are not planar, with dihedral angles of 37.52 (14) and 42.45 (14)° between the phenyl rings and...
متن کاملCrystal structure of 2-{[1-(4-bromobenzyl)-1H-1,2,3-triazol-4-yl]methoxy}naphthalene-1,4-dione
In the title compound, C20H14BrN3O3, the benzene ring makes dihedral angles of 71.30 (11) and 68.95 (14)° with the naphthalene ring system and the triazole ring, respectively. The latter two ring systems are coplanar, with a dihedral angle of 2.92 (12)°. The O atoms deviate from the naphthalene ring system by 0.029 (2) and -0.051 (2) Å. In the crystal, mol-ecules are linked by C-H⋯O and C-H⋯N h...
