Synthesis and crystal structure of [(PhenH)(PhenH(2))][BiCl6]center dot 2H(2)O with different o-phenanthroline protonations

The reaction between bismuthate oxide and phen (1,10-phenanthroline) in aci d medium led to the isolation of the unusual [(PhenH)(PhenH(2))][BiCl6]. 2H (2)O derivative, which has been characterized by X-ray analysis and IR spec troscopy. The compound crystallizes in the triclinic space group P (1) over bar with a = 8.313(2), b = 9.349(2), c = 9.807(3) Angstrom, alpha = 86.39( 3), beta = 110.27(3) and gamma = 106.48(3)degrees. The crystal structure is made of [BiCl6](3-) anions and [(PhenH)(PhenH(2))](3+) cations. A network of hydrogen bond interactions involving the two clathrated water molecules, the phenanthroline moiety and the chlorines characterizes the entire struc ture.
