Crystal structure of 2-(11-oxo-10H,11H-indeno-[1,2-b]chromen-10-yl)-2,3-di-hydro-1H-indene-1,3-dione.

ABSTRACT: 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 along the b axis. In addition, there is a ?-? stacking inter-action between the five-membered rings of adjacent fused-ring systems, with a centroid-centroid distance of 3.666?(1)?Å.

Crystal structure of 2-(5-bromo-2-hy-droxy-benzyl-idene)-2,3-di-hydro-1H-indene-1,3-dione.

Project description: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 ring with one of the indandione carbonyl O atoms stabilizes the mol-ecular conformation. In the crystal, the mol-ecules form dimers across centres of inversion via pairwise O-H?O hydrogen bonds. The dimers form stacks running parallel to [010] and inter-act through ?-? inter-actions between the five-membered ring of one mol-ecule and the six-membered rings of the indandione moiety of an adjacent mol-ecule [centroid-to-centroid distance = 3.5454?(10)?Å].

Crystal structures of three 1-oxo-1,2-di-hydro-naphthalene derivatives: dimethyl 4-(4-meth-oxy-phen-yl)-2-(4-methyl-phen-yl)-1-oxo-1,2-di-hydro-naphthalene-2,3-di-carboxyl-ate, dimethyl 1-oxo-2-(pyren-4-yl)-4-(thio-phen-2-yl)-1,2-di-hydro-naphthalene-2,3-di-carboxyl-ate and ethyl 1-oxo-2-phenyl-2,4-bis-(thio-phen-2-yl)-1,2-di-hydro-naphthalene-3-carboxyl-ate.

Project description:In the title 1-oxo-1,2-di-hydro-naphthalene derivatives, C28H24O6, (I), C34H22O5S, (II), and C27H20O3S2, (III), the cyclo-hexa-1,3-diene rings of the 1,2-di-hydro-naphthalene ring systems adopt half-chair, boat and half-chair conformations, respectively. The carbonyl O atoms attached to the di-hydro-naphthalene ring systems are each significantly deviated from the mean plane of the 1,2-di-hydro-naphthalene ring system, by 0.6162 (12) Å in (I), 0.6016 (16) Å in (II) and 0.515 (3) Å in (III). The mean planes of the 1,2-di-hydro-naphthalene ring systems make dihedral angles of 85.83 (3), 88.19 (3) and 81.67 (8)°, respectively, with the methyl-phenyl ring in (I), the pyrene ring in (II) and the phenyl ring in (III). In (I), the mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond, generating an S(6) ring motif. In the crystal of (I), mol-ecules are linked by an inter-molecular C-H⋯O hydrogen bond, which generates a C(8) zigzag chain running along [100]. Adjacent chains are further connected by C-H⋯π and offset π-π inter-actions [centroid-centroid distance = 3.6572 (9) Å], forming a double-chain structure. In the crystals of (II) and (III), mol-ecules are linked into chain structures by offset π-π inter-actions with centroid-centroid distances of 3.5349 (12) and 3.8845 (13) Å for (II) and 3.588 (2) Å for (III). In (II) and (III), the thio-phene rings are orientationally disordered over two sites, with occupancy ratios of 0.69:0.31 for (II), and 0.528 (4):0.472 (4) and 0.632 (5):0.368 (5) for (III).
