Abstract

The microwave spectrum of (η5-C5H5)W(CO)2NO was observed using a Flygare-Balle type pulsed beam spectrometer. Fourteen a-dipole transitions in the 5-10 GHz range were measured. Rotational constants obtained are A = 952.(1) MHz, B = 708.316(2) MHz, and C = 701.857(2) MHz. Structural parameters obtained from the data analysis are r(C5H5-W) = 2.06(3) Å, ∠C5H5-W-N = 122.7(10)°, and ∠C5H5-W-CO = 123.2(10)°. The difference between the nitrosyl and carbonyl angles with respect to the C5H5 symmetry axis is much smaller for this complex than for the C5H5Cr(CO)2NO complex.
