Abstract

Comproportionation reactions of rare-earth metal trihalides (RX3) with the respective rare-earth metals (R) and transition metals (T) led to the formation of 22 oligomeric R cluster halides encapsulating T, in 19 cases for the first time. The structures of these compounds were determined by single-crystal X-ray diffraction and are composed of trimers ({T3R11}X-15-type, P6(3)/m), tetramers ({T4R16}X-28{R-4} (P-43m), (T4R16}X-20 (P4(2)/nnm), {T4R16}X-24(RX3)(4) (I4(1)/a) and (T4R16}X-23 (C2/m) types of structure) and pentamers ({Ru5La14}(2)Br-39, Cc) of {TRr}(n) (n=2-5) clusters. These oligomers are further enveloped by inner (X-i) as well as outer (X-a) halido ligands, which possess diverse functionalities and interconnect like oligomers through i-i, i-a and/or a-i bridges. The general features of the crystal structures for these new compounds are discussed and compared to literature entries as well as different structure types with oligomeric T centered R clusters. Dimers and tetramers originating from the aggregation of {TR6} octahedra via common edges are more frequent than trimers and pentamers, in which the {TRr} clusters share common faces.
