5-methylcyclopentadienyl)tungstenAbstract: The title complex, [W(5-C5H5CH3)I(CO)3], lies on a crystallographic mirror plane, with only one half-molecule per asymmetric unit. This four-legged piano-stool tungsten complex is strained at the W atom, with the trans-C-W-I angle [130.93 (18)°] larger than the cis-C-W-C angle [111.1 (3)°]. A possible trans influence due to a larger ![[pi]](/logos/entities/pi_rmgif.gif)
back-bonding is marginal, with an insignificant difference between the W-C bond length trans to I [1.984 (6) Å] and the other W-CCO bond lengths [1.996 (5) Å].
