Abstract:
We have been able, via a new synthetic route, to obtain a complete crystal structure of the title compound, tetraaquabarium hydroxide iodide, [Ba(OH)I(H(2)O)(4)], for which the heavy atoms only were characterized by Kellersohn, Beckenkamp & Lutz [Z. Naturforsch. Teil B (1991), 46, 1279-1286]. In the present results, the H-atom positions could be located using X-ray data collection at low temperature. A three-dimensional network is built up via hydrogen bonds. It was also observed that the title compound undergoes hydrolysis and might therefore be regarded as an intermediate in the formation of sol-gels, starting from BaI(2) and leading to [Ba(OH)(2)(H(2)O)(x)].
