2-(3-Bromopropyl)isoindoline-1,3-dione
In the title compound, C(11)H(10)BrNO(2), the dihedral angle between the five- and six-membered rings of the phthalamide system is 1.00 (16)°. There are no significant inter-molecular inter-ations except for van der Waals contacts.

In the title compound, C(24)H(23)NO(2)Si, the dihedral angle between the planes of the phenyl rings attached to the Si atom is 80.78 (10)°. In the crystal, the mol-ecules form sheets lying perpendicular to [101] via C-H⋯O inter-actions. These sheets are stacked and linked in a three-dimensional framework by additional C-H⋯O inter-actions in the [10] direction.

In the indane ring system of the title mol-ecule, C(13)H(12)O(4), the hy-droxy-bearing C atom is 0.134 (1) Å out of the plane of the remaining essentially planar atoms (r.m.s. deviation = 0.010 Å). In the crystal, mol-ecules are linked into chains along the b axis by inter-molecular O-H⋯O hydrogen bonds. Additional stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds.

In the title mol-ecule, C(24)H(18)ClNO(6)S, the heterocyclic thia-zine ring adopts a half chair conformation with the S and N atoms displaced by 0.318 (3) and 0.387 (3) Å, respectively, on the opposite sides from the mean plane formed by the remaining ring atoms. The benzene rings of the benzothia-zin unit and meth-oxy-benzoyl group are more or less coplanar, the dihedral angle between the mean...
متن کامل2-[2-(3-Chlorophenyl)hydrazinylidene]-1,3-diphenylpropane-1,3-dione
The mol-ecular structure of the title compound, C(21)H(15)ClN(2)O(2), features one strong intra-molecular N-H⋯O resonance-assisted hydrogen bond (RAHB). In the crystal, mol-ecules form inversion-related dimers via pairs of weak inter-molecular N-H⋯O contacts. These dimers are further stabilized via three weak C-H⋯O contacts, developing the three-dimensional structure.
