Sažetak
Crystallochemistry of the novel oxobromides (RE)TagBr1803 with RE = Sm to Lu (except Eu and Yb) is reported. All these compounds, which exhibit 14 valence electrons per Tag cluster, are isotypic with ScNbgCl^Og with the space group 74x22. The structure of LuTagBrxgOg has been determined from single crystal X-ray diffraction: a = 9.383(1) Å and c = 54.60(1) Å, R = 0.050 and Rw = 0.054 for 755 symmetry-independent reflections. For this compound, the (TagL18) units (L = Br and O), in which the Tag cluster is very distorted, are linked together by four bridging bromines to form pseudo-helices of units. The lutetium is five-coordinated at a small site formed by three oxygen and two bromine atoms belonging to three adjacent units. The formula developed for this compound is Lu(TagBr91031)Br2aBr4/2a_a. These structural results allow discussion of the influence of interatomic distances on the potential properties of these novel ternary tantalum oxobromides in relation to the oxidation state of the cluster.
