1-Cyanomethyl-1,4-diazoniabicyclo[2.2.2]octane tetrachloridocadmate(II)  [cached]
Yi Zhang,Bo Han Zhu
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536812017801
Abstract: In the title salt, (C8H15N3)[CdCl4], four Cl atoms coordinate the CdII atom in a slightly distorted tetrahedral geometry. In the crystal, each [CdCl4]2 anion is connected to the 1-cyanomethyl-1,4-diazoniabicyclo[2.2.2]octane dications by N—H...Cl hydrogen bonds, forming chains parallel to [001]. C—H...Cl interactions also occur.

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811025347
Abstract: In the title compound, (C8H18N2)[CuCl4], torsion angles on the ethylene bridges of the 1,4-diazoniabicyclo[2.2.2]octane fragment are in the range 11.9 (5)–15.0 (5)° and the [CuCl4]2 anion has a strongly distorted tetrahedral geometry. The cation is connected to the anion via three-center N—H...Cl hydrogen bonds.

Li-Zhuang Chen
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810007865
Abstract: In the title compound, C6H14N22+·Cl4I ·Cl , the dication and the anions lie on special positions. The dication has mm2 symmetry with two bonded C atoms and the two N atoms located on a crystallographic mirror plane parallel to bc, and with a mirror plane parallel to ab passing through the mid points of the three C—C bonds. In the square-planar Cl4I anion, two Cl atoms and the I atom are located on the mm2 axis; the other two Cl atoms are disordered over two postions of equal occupancy (0.25) across the mirror parallel to the ab plane. The Cl anion is located on the mm2 axis. The crystal structure is stabilized by intermolecular N—H...Cl hydrogen bonds.
