N2  - The room-temperature single-crystal X-ray structural characterization of the title compound (tpyH2)2[Tb(OH2)8]Cl7.~2&#8531;H2O is recorded. Crystals are triclinic, P&#299; , a 17.063(5), b 16.243(3), c 7.878(3) &#506;, &#945; 84.78(2), &#946; 84.39(3), &#947; 87.81(2)&#176;, Z = 2 formula units; 3167 'observed' diffractometer reflections were refined by full-matrix least-squares procedures to a residual of 0.057. Notable features of interest of the compound are the 'chelation' of chloride ions by the terpyridinium cations , and the existence of a free [Tb(OH2)8]2+ cation in the presence of an abundance of chloride ions.
