[edit] Interatomic angles and lengths

The interatomic angles and lengths given in the text are different from those presented in the accompanying space-filling model graphic, with no explanation given in the text. Doonhamer 04:48, 23 March 2007 (UTC)

I made the image. I obtained the bond lengths and angles from Greenwood, N. N.; Earnshaw, A. (1997). Chemistry of the Elements, 2nd Edition, Oxford:Butterworth-Heinemann. ISBN 0-7506-3365-4. . Perhaps the text refers to HOF in the solid phase while the dimensions in my diagram refer to HOF in the gas phase. Bond lengths and angles are often different in different phases.

Thanks Ben. I'm not very knowledgeable in the area. Maybe this can be mentioned in the article? Doonhamer 13:53, 7 April 2007 (UTC)

Done. Thanks for raising awareness of this contradiction.
Cheers

The angles still dont jive.--Smokefoot 15:42, 7 April 2007 (UTC)
Sorry about removing the title of the reference - I'm not used to using <ref> tags. What do you mean by jive?

The figure and the text dont agree on the H-O-F angle. I dont have the original paper anymore, so I dont which is correct.

--Smokefoot 16:28, 7 April 2007 (UTC)

Greenwood and Earnshaw gives the both angles, the one in the figure from spectroscopic data (gas phase) and the one in the text from x-ray diffraction (solid phase). They're both correct, aren't they?

Oh, thanks... I hadnt realized. --Smokefoot 17:30, 7 April 2007 (UTC)

I rewrote the paragraph discussing the solid phase bond measurements to make clear the reason for the discrepancy with the illustration. Good work everyone. Doonhamer 06:53, 8 April 2007 (UTC)
