چکیده
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 organic-inorganic hybrid, {(C(6)H(13)N(3))(2)[Pb(3)I(10)]}(n), was obtained by the reaction of 1-(3-ammonio-prop-yl)imidazolium triiodide and PbI(2) at room temperature. The structure contains one-dimensional {[Pb(3)I(10)](4-)}(n) polymeric anions spreading parallel to [001], resulting from face-face-edge association of PbI(6) distorted octa-hedra. One of the Pb(II) cations is imposed at an...
