Bis(4-chloro-pyridinium) tetra-chlorido-nickelate(II).

ABSTRACT: In the title compound, (C(5)H(5)ClN)(2)[NiCl(4)], the dianion lies on a twofold rotation axis. Two cations are linked to each anion by classical N-H?Cl hydrogen bonds, and short Cl?Cl contacts and Cl?? stacking inter-actions [with distances of 3.376?(2) and 3.684?(2)?Å, respectively] extend this pattern into a chain. The [NiCl(4)](2-) anion shows significant deviation from ideal tetra-hedral geometry.

In the title compound, (C(5)H(5)ClN)(2)[NiCl(4)], the dianion lies on a twofold rotation axis. Two cations are linked to each anion by classical N-H⋯Cl hydrogen bonds, and short Cl⋯Cl contacts and Cl⋯π stacking inter-actions [with distances of 3.376 (2) and 3.684 (2) Å, respectively] extend this pattern into a chain. The [NiCl(4)](2-) anion shows significant deviation from ideal tetra-hedral geometry. ...[more]
