ABSTRACT
The title mol-ecule, C(9)H(6)ClNO(2), is essentially planar: the maximum deviation from the mean plane of the indoline ring is 0.020â (2)â Å and the substituents do not deviate by more than 0.053â (2)â Å from this plane. C-Hâ¯O hydrogen bonds help to consolidate the crystal structure.
ABSTRACT
In the title compound, C(11)H(8)Cl(2)N(2)O(2)·H(2)O, the dihedral angle between the benzene and isoxazole rings is 59.10â (7)°. In the crystal, the components are linked by N-Hâ¯O and O-Hâ¯O hydrogen bonds into a three-dimensional network. The crystal structure is further stabilized by π-π stacking inter-actions [centroid-centroid distance = 3.804â (2)â Å].
ABSTRACT
In the title compound, C(15)H(10)ClNO(2),the dihedral angle between the mean planes of the benzene and 6-chloro-indoline-2,3-dione ring systems, linked through a methyl-ene group, is 81.68â (10)°. In the crystal, mol-ecules are connected by C-Hâ¯O hydrogen bonds, generating C(6) chains propagating in [010].
ABSTRACT
In the title compound, C(6)H(10)ClNO, an inter-mediate for the production of lysine, there are intra-molecular C-Hâ¯Cl hydrogen bonds.
ABSTRACT
In the crystal structure of the title compound, C(13)H(14)ClNO(2), inter-molecular C-Hâ¯O inter-actions link the mol-ecules into a two-dimensional network.
ABSTRACT
The asymmetric unit of the title compound, C(11)H(11)BrN(2)O(4), contains two crystallographically independent mol-ecules in which the bromo-phenyl rings are oriented at dihedral angles of 39.28â (3)°. The dioxolane rings adopt envelope conformations. Intra-molecular N-Hâ¯O hydrogen bonds result in the formation of four five-membered rings, having planar and envelope conformations. In the crystal structure, inter-molecular N-Hâ¯O hydrogen bonds link mol-ecules into chains along the b axis, forming R(2) (2)(8) ring motifs.
ABSTRACT
The title compound, C(11)H(11)ClN(2)O(4), is an important inter-mediate for the preparation of platinum anti-cancer drugs. The dioxolane ring adopts a twist conformation with an equatorially attached chloro-phenyl substituent. In the crystal structure, mol-ecules are linked into a two-dimensional network parallel to (001) by N-Hâ¯O and C-Hâ¯O hydrogen bonds.
