Glycine zinc sulfate penta-hydrate: redetermination at 10 K from time-of-flight neutron Laue diffraction.

ABSTRACT: Single crystals of glycine zinc sulfate penta-hydrate [systematic name: hexa-aqua-zinc tetra-aquadiglycinezinc bis-(sulfate)], [Zn(H₂O)₆][Zn(C₂H₅NO₂)₂(H₂O)₄](SO₄)₂, have been grown by isothermal evaporation from aqueous solution at room temperature and characterized by single-crystal neutron diffraction. The unit cell contains two unique ZnO₆ octa-hedra on sites of symmetry -1 and two SO₄ tetra-hedra with site symmetry 1; the octa-hedra comprise one [tetra-aqua-diglycine zinc]²⁺ ion (centred on one Zn atom) and one [hexa-aqua-zinc]²⁺ ion (centred on the other Zn atom); the glycine zwitterion, NH₃⁺CH₂COO
