摘要：

The crystal and molecular structure of the title compound, (CH7N4)(CH8N4)[SbCl6], has been determined at 295 and 92 K. It is composed of isolated [SbCl6](3-) octahedra and aminoguanidinium mono- and dications. One of four of the crystallographically inequivalent aminoguanidinium cations is disordered at both temperatures. Two crystallographically inequivalent [SbCl6](3-) octahedra were found to possess three significantly longer Sb-Cl bonds than three other octahedra. The shorter bonds are in the range 2.456 (2)-2.577 (2) Angstrom, whereas the longer ones are between 2.705 (2) and 2.931 (2) Angstrom. Each short Sb-Cl bond is located trans to a long bond. It is argued that this deformation is caused by ND H . . . Cl hydrogen bonds.
