Liberation Fonts Increase Interoperability For Linux Users
hweimer writes "Most problems when opening Word documents under GNU/Linux are due to missing fonts. Therefore, Red Hat published a set of fonts metric-compatible with the Windows core fonts last year. However, there were some concerns regarding the licensing that prevented many other distros to ship them. We finally managed to settle these problems, leading to better document interoperability for all GNU/Linux users."

Like Arial is rather similar to Helvetica. Some people claim that Microsoft did this to avoid paying royalties, see also http://en.wikipedia.org/wiki/Arial#Criticism.2FSimilar_fonts.
Now this may be true or not, but after they almost copied Helvetica with Arial, turnabout's fair play.

Gentium. It's released under the Open Font License, which I believe is "free" (by the FSF's definition).
It was also designed with many extended Latin characters, allowing ethnic groups across the world to produce documents typeset in Gentium. (I mean, just look at all these diacritics!)
Say what you want about the organization that produced these (SIL International), but this is a good-looking, high-quality typeface, which fits your criteria perfectly.
We had Word documents get so screwed up that Word wouldn't open them. The best fix was to open them in OpenOffice and re-save them. It messed up the formatting, but it was better than losing a days work. I keep it around as a repair tool even in an all MS shop.
If you think Word is evil, stay away from Publisher.
