While the single acceptor H-bond is most common, bifurcated (or three-centred) H-bods are not uncommon in crystal structures, as described starting page 22 of GA Jeffrey's book: http://www.amazon.com/Introduction-Hydrogen-Bonding-Physical-Chemistry/dp/0195095499/ref=sr_1_2?ie=UTF8&qid=1322331503&sr=8-2
