11. The W≡E bond distances calculated from the W≡E force constants (Table 1) using the Woodruff equations (d(W≡N) = 1.70 Å, d(W≡P) = 2.20 Å; ref 10) are in excellent agreement with the observed (or estimated) distances, while those calculated from Badger's rule (eq 7 and Table 1 in ref 9) and from the Herschbach-Laurie relationship (eq 8 and Table 2 in ref 9) are in poorer agreement. The disagreement for the latter two relationships undoubtedly reflects the limitations of the parameters available for heteronuclear diatomic compounds, as illustrated by a recent reparameterization for homonuclear species (Harvey, P. D. Coord. Chem. Rev. 1996, 153, 175).
