The reaction of ruthenocene carboxylic acid (RcCOOH) with [n-BuSn(O)OH]_n, (Ph₃Sn)₂O, and (PhCH₂)₃SnCl afforded hexameric compounds [RSn(O)OOCRc]₆, R = n-Bu (1), Ph (2), and PhCH₂ (3), respectively. These possess a prismane type Sn₆O₆ core which supports a hexa-ruthenocene periphery. Compounds [{n-Bu₂Sn}₂(渭₃-O)OOCRc₂]₂ (4) and [n-Bu₂Sn(OOCRc)₂](5) were formed in the reaction of RcCOOH with n-Bu₂SnO in 1:1 and 2:1 reactions, respectively. Compound [t-Bu₂Sn(渭鈥揙H)OOCRc]₂ (6) is a dimer containing two ruthenocene units, and it was formed in the reaction of RcCOOH with (t-Bu₂SnO)₃ in a 3:1 ratio. Compounds 1鈥?b>6 show an extensive supramolecular organization in the solid state as a result of several intermolecular interactions. Compound 1 could be converted quantitatively to a pure phase of the binary oxide, (RuSn)O₂ at 400 掳C.
