link (http://books.google.com.ar/books?id=HyuogOtzoaYC&pg=PA52&lpg=PA52&dq=sp5+orbitals&source=bl&ots=1pg5u7yWyB&sig=lrNFvKKhium_sUfeZj0gmkdORRU&hl=es-419&sa=X&ei=ijJeT6O4G8iztwftmKn4Dg&ved=0CEYQ6AEwBQ#v=onepage&q=sp5%20orbitals&f=false)
any explanation? =(
Morrison also talks about it, it says something about the p character of a bond
Edit by Borek: too long link modified

It appears to be a mathematical construction to fit the electron distribution data. What you must remember is hybridisation is just a way of expressing bond character, it isn't what actually happens (MO theory is the one that describes the structure as best as we can), so these mathematical constructions can be made. But I wouldn't worry about it too much, it's un-important.

I couldn't even get the page to load, so I'm in no position to contradict.

Can't load the link either, but some googling has shown that some people like to describe cyclopropanes as having bonds made out of sp5 orbitals (17% s, 83% p). Unless one's crunching numbers in theoretical chemistry, saying that these bonds have increased p-character, without slapping numbers on it, is a lot simpler.
