(E)-Methyl 3-(1H-indol-2-yl)acrylate

The title compound, C12H11NO2, is close to being planar (r.m.s. deviation for the non-H atoms = 0.033 Å). In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds, generating C(7) chains running along the b axis. A weak C—H⋯O interaction helps to establish the packing

The title compound, C13H20O3S5, is bis­ected by a crystallographic twofold rotation axis, which relates the two halves of the mol­ecule to one another: one S, one C and one O atom lie on the axis. The thione S atom lies in the plane of the five-membered rings with an r.m.s. deviation of 0.0042 (5) Å. Parts of the 17-membered macrocycle were refined using a two-part disorder model [occupancies of 0.553 (14) and 0.447 (14)]. There are no noteworthy inter­molecular inter­actions

In the title mol­ecule, C11H16O2S5, the two S atoms from the macrocycle are situated on opposite sides of the mean plane of the five-membered ring, deviating from it by 1.288 (3) and 1.728 (3) Å. In the crystal, weak inter­molecular C—H⋯S and C—H⋯O hydrogen bonds link the mol­ecules into layers parallel to (100). The crystal studied was a racemic twin

In the title mol­ecule, C14H18OS8, one O atom, two S atoms and six C atoms form an 11-membered ring with a chair-like conformation; the planes of the two five-membered rings connected by a carbon–carbon double bond form a dihedral angle of 29.97 (11)°. In the crystal, pairs of weak inter­molecular C—H⋯S hydrogen bonds link two mol­ecules into inversion dimers

1-(1,3-Benzothia­zol-2-yl)-3-phenyl-2-pyrazoline
