• The crystal structures of (1,5-cyclooctadiene)di-μ-methoxo-dirhodium(I) and tetrakis(η<SUP>3</SUP>-allyl)di-μ-hydroxodirhodium(III) were determined by the X-ray method. The former belongs to the triclinic space group P\bar1 with cell dimensions, <I>a</I>=7.347(4), <I>b</I>=6.471(3), <I>c</I>=9.554(6) Å, α=87.06(4), β=82.50(5) and γ=77.98(4)°. The space group of the latter is also P\bar1 but two crystallographically independent molecules exist in a cell with dimensions, <I>a</I>=11.704(7), <I>b</I>=9.793(6), <I>c</I>=7.948(5) Å, α=113.49(5), β=54.59(5), and γ=110.99(5)°. Both structures were determined by the heavy atom method and refined by the block-diagonal least-squares method. The final <I>R</I> values were 0.054 for the former and 0.075 for the latter. The coordination of the rhodium atom in the former compound is square planar, the cyclooctadiene ligand being regarded as a bidentate donor. The latter coordination is, in a formal sense, octahedral.
