Crystal structure of 2-(1,3-dioxoindan-2-yl)iso-quinoline-1,3,4-trione.

ABSTRACT: In the title iso-quinoline-1,3,4-trione derivative, C18H9NO5, the five-membered ring of the indane fragment adopts an envelope conformation with the nitro-gen-substituted C atom being the flap. The planes of the indane benzene ring and the iso-quinoline-1,3,4-trione ring make a dihedral angle of 82.06 (6)°. In the crystal, mol-ecules are linked into chains extending along the bc plane via C-H⋯O hydrogen-bonding inter-actions, enclosing R 2 (2)(8) and R 2 (2)(10) loops. The chains are further connected by π-π stacking inter-ations, with centroid-to-centroid distances of 3.9050 (7) Å, forming layers parallel to the b axis.

Project description:In the title solvated compound, C28H19N2O4·C2H6OS, the central β-lactam ring is almost planar (r.m.s. deviation = 0.002 Å). It makes dihedral angles of 1.92 (11), 83.23 (12) and 74.90 (10)° with the meth-oxy- and chloro-phenyl rings and the ring plane of the 1H-benzo[de]iso-quinoline-1,3(2H)-dione group [maximum deviation = 0.089 (1)], respectively. An intra-molecular C-H⋯O hydrogen bond closes an S(6) ring and helps to establish the near coplanarity of the β-lactam and meth-oxy-benzene rings. In the crystal, the components are linked by C-H⋯O hydrogen bonds, C-H⋯π inter-actions and aromatic π-π stacking inter-actions [centroid-to-centroid distances = 3.6166 (10) and 3.7159 (10) Å], resulting in a three-dimensional network, The dimethyl sulfoxide solvent mol-ecule is disordered over two sets of sites in a 0.847 (2):0.153 (2) ratio.

Crystal structure of 5-(1,3-di-thian-2-yl)-2H-1,3-benzodioxole.

Project description:In the title compound, C11H12O2S2, two independent but virtually superimposable mol-ecules, A and B, comprise the asymmetric unit. In each mol-ecule, the 1,3-di-thiane ring has a chair conformation with the 1,4-disposed C atoms being above and below the plane through the remaining four atoms. The substituted benzene ring occupies an equatorial position in each case and forms dihedral angles of 85.62 (9) (mol-ecule A) and 85.69 (8)° (mol-ecule B) with the least-squares plane through the 1,3-di-thiane ring. The difference between the mol-ecules rests in the conformation of the five-membered 1,3-dioxole ring which is an envelope in mol-ecule A (the methyl-ene C atom is the flap) and almost planar in mol-ecule B (r.m.s. deviation = 0.046 Å). In the crystal, mol-ecules of A self-associate into supra-molecular zigzag chains (generated by glide symmetry along the c axis) via methyl-ene C-H⋯π inter-actions. Mol-ecules of B form similar chains. The chains pack with no specific directional inter-molecular inter-actions between them.
