%X A structural analysis of [(&#951;-C5H5)2YMe2AlMe2] has been carried out by X- ray diffraction. Crystals are orthorhombic, space group Pna21, a 17.969(6), b 7.988(4), c 10.870(4) &#506;, Z 4. The structure has been refined by a full-matrix least-squares procedure to R 0.052 for 663 observed reflections (Mo K&#945; automatic diffractometry). The structure contains a dimethyl bridge, the average bridging bond distances being 2.58(3) &#506; for Y-C and 2.10(2) &#506; for Al-C, and the Y-Al separation is 3.056(6) &#506;.
