Crystal structure of two homochiral metal-organic polymers based on S-3,3-dimethyllactic acid

Resumo

By heating of an aqueous solution of zinc(II) or cobalt(II) acetates, 4,4-bipyridyl (bpy), and S-3,3-dimethyl hydroxypropionic acid (H₂dml) two homochiral coordination polymers [Zn(H₂O)(bpy)(Hdml)](CH₃COO)∙ ∙2H₂O (1) and [Co(H₂O)(bpy)(Hdml)₂] (2) are obtained. The crystal structure is determined by single crystal X-ray diffraction. Compound 1 has a layered structure and compound 2 has a chain structure.
