Poly[dimethyl-ammonium [aquadi-μ(2)-oxalato-dysprosate(III)] trihydrate].

ABSTRACT: The title compound, {(C(2)H(8)N)[Dy(C(2)O(4))(2)(H(2)O)]·3H(2)O}(n), was obtained as an unexpected product under hydro-thermal conditions. The Dy(III) atom is chelated by four oxalate anions, two of which are situated on two different centres of inversion. The distorted tricapped trigonal-prismatic coordination sphere of the Dy(III) atom is completed by a water mol-ecule. The bridging mode of the anions results in the formation of a three-dimensional network with cavities where the ammonium cations and the uncoordinated water mol-ecules reside. The structure is stabilized by numerous N-H⋯O and O-H⋯O hydrogen-bonding inter-actions.
