title: Yttrium bisphosphonate STA-13: a racemic phosphonate metal organic framework with permanent microporosity.
abstract: Crystallisation of yttrium and other trivalent metal cations of similar radius with racemic N,N'-2-methylpiperazinebis(methylene phosphonic acid) gives a small pore bisphosphonate metal-organic framework solid displaying coordinative and hydrogen bonding and permanent porosity.
