On Two Glycine Zinc Sulfate Phases with Exotic Cation Coordination Geometries

Abstract

Abstract. Two hitherto hardly characterized glycine zinc sulfates were identified in the product of a batch production process for glycine zinc sulfates of the BASF Company: Gly·ZnSO 4 ·2H 2 O and β-Gly-ZnSO 4 . The crystal structures were solved from high resolution synchrotron X-ray powder diffraction data. Gly·ZnSO 4 ·2H 2 O is the zinc analogue to an isotypic copper compound with space group P2 1 /c (no. 14) and a = 7.8092(1) Å, b = 12.3979(2) Å, c = 8.3732(1) Å, β = 90.673(1) and V = 810.62(2) Å 3 .
