Structure of hydrated dysprosium picolinate, [Dy(C5H4NCO2)(3)(H2O)(2)]2.8H(2)O

The crystal structure of the title compound was determined by X-ray diffraction. The dysprosium ion is eight-coordinated by three oxygen atoms and three nitrogen atoms from three picolinato ions and two water oxygen atoms. The nitrogen atom and one carboxyl oxygen atom of each picolinato ion are coordinated to the same dysprosium ion to form a five-membered chelating ring. The title compound exists as discrete molecules in the crystal structure.
