1-[Bicyclo[4.2.0]octa-1(6),2,4-trien-3-yl]-3-(but-3-enyl)imidazolium bromide
In the title compound, C(15)H(17)N(2) (+)·Br(-), the cyclo-butene and benzene rings are coplanar. The dihedral angle between the benzene and imidazolium rings is 21.2 (3)°. In the crystal structure, the C(15)H(17)N(2) (+) and Br(-) ions are linked into a zigzag chain along the b axis by C-H⋯Br hydrogen bonds, and weak C-H⋯π inter-actions involving the benzene ring of a screw-related cation.

In the title compound, C(20)H(19)N(2) (+)·PF(6) (-), the two benzocyclo-butene units are essentially planar and they form dihedral angles of 38.0 (2) and 72.7 (2)°, with the central imidazolium ring. In the crystal structure, weak C-H⋯π and π--π stacking inter-actions [centroid-centroid distance = 3.742 (2) Å] contribute to the stability of the crystal structure. The PF(6) (-) ion is disordered...

The title mol-ecule, C(13)H(17)ClN(3)OS(+)·Br(-), consists of benzene and pyrrolidine rings and an S-C(NHCH(3))(2) group. The central C-N bond lengths in the S-C(NHCH(3))(2) fragment indicate partial double-bond character. Mol-ecules are inter-connected into chains by N-H⋯Br hydrogen bonds and the chains are linked into pairs by weak C-H⋯Br hydrogen bonds.

The title compound, C(23)H(18)N(2)O(2)·0.5H(2)O, a derivative of the biologically active compound curcumin, crystallizes with two organic mol-ecules and a solvent water mol-ecule in the asymmetric unit. Each of the two independent mol-ecules is close to being planar (the dihedral angles between the indole ring systems are approximately 9 and 12°) and each exists in the keto-enol form. There is ...

In the title molecular salt, C(11)H(13)ClN(3)OS(+)·Br(-), the C-N bond lengths in the -S-C(NH(2))(2) fragment indicate partial double-bond character of these bonds. The constituent ions are connected by N-H⋯Br bridges into Z-shaped chains. The supra-molecular architecture of the structure can be described by being composed of these chains inter-locked by additional C-H⋯Br short contacts. An int...
