The crystal structure of the title compound, C₁₅H₂₈ClN₅, is stabilized by inter­molecular N—HN hydrogen bonds.

In the title ion-pair compound, (C₁₆H₁₃N₂O₂)[Pd(C₃S₅)₂]·C₃H₆O, the Pd^III atom exhibits square-planar coordination geometry involving four S atoms of two 2-thioxo-1,3-dithiole-4,5-dithiol­ate (dmit) ligands. Some weak SS inter­actions and hydrogen bonds are found, resulting in a three-dimensional supra­molecular network structure.

The title compound, (C₁₃H₁₀BrN₂)[Ni(C₃S₅)₂]·C₃H₆O, is a new ionic complex in which the Ni^III atom exhibits a square-planar coordination involving four S atoms from two 2-thioxo-1,3-dithiole-4,5-dithiol­ate (dmit) ligands. In the crystal structure, weak SS and hydrogen-bonding inter­actions form a three-dimensional supra­molecular network.
