The crystal structure of the title compound was determined by X-ray di
ffraction. The dysprosium ion is eight-coordinated by three oxygen ato
ms and three nitrogen atoms from three picolinato ions and two water o
xygen atoms. The nitrogen atom and one carboxyl oxygen atom of each pi
colinato ion are coordinated to the same dysprosium ion to form a five
-membered chelating ring. The title compound exists as discrete molecu
les in the crystal structure.
