Abstract
In the crystal structure of the cluster salt, [Ta6I12(H2O)6]I2·4H2O, the octa-hedral {Ta6} cluster core is μ2-coordinated by twelve iodido ligands (inner ligand sphere) whereas the six aqua ligands coordinate each at the six outer positions. The discrete, inversion-symmetric cluster complex is double-positively charged, and two iodide anions are present in the crystal structure as counter-ions. In addition, four water mol-ecules are co-crystallized. Hydrogen bonds between the cluster unit, the iodide anions and co-crystallized water mol-ecules stabilize the charge-assisted packing in the crystal structure.

Starting from the well-known compound [Ta6I14] (Bauer et al, 1965), the title compound [Ta6I12(H2O)6]I2Á4H2O was obtained by reaction with a water–acetone mixture and subsequent evaporation of the solvent. This compound was previously mentioned by Schafer et al (1972) and Shamshurin et al (2019), without determination of its crystal structure. [Ta6I12(H2O)6]I2Á4H2O can be used efficiently as a precursor for new tantalum cluster compounds
