    Crystal structure of posnjakite formed in the first crystal water-cooling line of the ANSTO Melbourne Australian Synchrotron MX1 Double Crystal Monochromator

    Exceptionally large crystals of posnjakite, CuSO(OH)(HO), formed during corrosion of a Swagelock(tm) Snubber copper gasket within the MX1 beamline at the ANSTO-Melbourne, Australian Synchrotron. The crystal structure was solved using synchrotron radiation to = 0.029 and revealed a structure based upon [Cu(OH)(HO)O] sheets, which contain Jahn-Teller-distorted Cu octa-hedra. The sulfate tetra-hedra are bonded to one side of the sheet corner sharing and linked to successive sheets extensive hydrogen bonds. The sulfate tetra-hedra are split and rotated, which enables additional hydrogen bonds. © Mills et al. 2020.
