Polydimethyl­ammonium aquadi-μ2-oxalato-dysprosate(III) trihydrate

摘要

The title compound, {(C2H8N)[Dy(C2O4)2(H2O)]·3H2O}n, was obtained as an unexpected product under hydro­thermal 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 mol­ecule. 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 mol­ecules reside. The structure is stabilized by numerous N—H⋯O and O—H⋯O hydrogen-bonding inter­actions.
