Abstract

Microwave rotational transitions for HMn(CO)₅ with ¹³C isotopic substitution in the axial and in one equatorial site were measured using a Flygare-Balle-type pulsed-beam spectrometer. Rotational constants obtained are A = B = 903.433(1) MHz for the axial ¹³CO isotopomer and A = 902.278(3) MHz and B = 907.761(3) MHz for the isotopomer with one equatorial ¹³C substitution. The new data are combined with previous data on HMn(CO)₅ and DMn(CO)₅ to obtain structural parameters for this complex. The Mn-H bond length obtained is r(Mn-H) = 1.65(2) Å and ∠C_ax-Mn-C_eq = 97.0(5)°.
