چکیده
The title compound, {Na(2)[Mg(2)(C(2)O(4))(3)(H(2)O)(2)]}(n), is isotypic with its Co analogue. There are two crystallographically independent oxalate groups in the asymmetric unit, one lying on an inversion center and the other on a general position. Mg(2+) ions are ligated by H(2)O mol-ecules and bridged by tri- and tetra-dentate oxalate ligands, forming ladder-like double chains that are held together via O-H⋯O hydrogen bonds, with Na(+) cations located between the chains to balance the charge.

In the paper by Hong, Song & Wu [Acta Cryst. (2007), E63, o2296], the scheme shows the wrong structure. The correct scheme is shown below and the compound name is corrected to "poly[[di-μ(2)-aqua-diaqua-hemi-μ(6)-oxalato-barium(II)] 2,4,6-trinitro-phenolate monohydrate", {[Ba(C(2)O(4))(0.5)(H(2)O)(4)]C(6)H(2)N(3)O(7)·H(2)O}(n).[This corrects the article DOI: 10.1107/S1600536807038159.].

In the title compound, {[Pr(2)(C(2)O(4))(3)(H(2)O)(4)]·2H(2)O}(n), the three-dimensional network structure has the Pr(III) ion coordinated by nine O atoms in a distorted tricapped trigonal-prismatic geometry. The coordinated and uncoordinated water mol-ecules inter-act with the carboxyl-ate O atoms to consolidate the network via O-H⋯O hydrogen bonds.

The title compound, [Cu(2)(C(2)O(4))(2)(C(3)H(4)N(2))(2)](n), was obtained as an unexpected product under hydro-thermal conditions. The Cu(II) atom is in a Jahn-Teller-distorted octa-hedral environment formed by one imidazole N atom and five O atoms from three oxalate anions. The two independent oxalate anions are situated on centres of inversion and coordinate to the Cu(II) atom in two differe...
