Solid-State Characterization of Enantiomeric and Racemic Hydrated and Anhydrous Zinc-Pidolate Complexes
Abstract
Zn(II) L- and DL-pidolates diaqua complexes dehydrate at around 407 K, leading to amorphous anhydrous complexes. Only amorphous anhydrous Zn(II) L-pidolate was found to crystallize on heating into a crystalline anhydrous phase whose crystal structure was solved from a high-resolution X-ray powder diffraction pattern. Orthorhombic anhydrous Zn(II) L-pidolate exhibits a structure in which (4 + 2)-coordinated Zn atoms (with four usual and two additional Zn-O distances of 2.53 and 2.69 Å) and L-pidolate ligands alternate so as to form a three-dimensional polymerized network. Room-temperature rehydration processes under saturating water vapor for amorphous and crystalline anhydrous complexes were found to be different from each other, although they all led back to crystalline diaqua complexes whose relative stabilities were inferred from measurements of their solubilities in water.
