Abstract: | Heterometallic chloride complexes Mo5NbI8Cl6]
n− (n = 2, 3) are synthesized. The crystal structures of their salts are determined: for (Ph4P)2Mo5NbI8Cl6] (I), triclinic crystal system, spacegroup P

The geometric parameters of compounds I and II and the conditions for the formation of the complexes with the charges −2 and −3 are discussed. |
