摘要:
The crystal structures of three compounds of glycine and inorganic materials are presented and discussed. The orthorhombic structure of glycinesulfatodilithium(I), [Li-2(SO4)(C2H5NO2)](n), consists of corrugated sheets of [LiO4] and [ SO4] tetrahedra. The glycine molecules are located between these sheets. The main features of the monoclinic structure of diaquadichloroglycinenickel(II), [NiCl2(C2H5NO2)(H2O)(2)](n), are helical chains of [NiO4Cl2] octahedra connected by glycine molecules. The orthorhombic structure of triaquaglycinesulfatozinc(II), [Zn(SO4)(C2H5NO2)(H2O)(3)](n), is made up of [O3SOZnO5] clusters. These clusters are linked by glycine molecules into zigzag chains. All three compounds are examples of non-centrosymmetric glycine compounds.
