Rb2Co(C2O4)2·4H2O consists of isolated [Co(C2O4)2·2H2O] octahedra which are connected only by hydrogen bonding of the water molecules. Rb2CoCl2(C2O4) consists of chains of Co2+ cations connected via oxalate bridging ligands. In K2Li2Cu(C2O4)3·2H2O, the metal cations are interconnected by oxalate ligands forming a novel three-periodic network.

The polymorphism of Na[Rh(H2O)2(C2O4)2]·2H2O is noteworthy. The complex crystallizes with the formation of two different structures of the same water content. Oxalato-rhodic acid not only exists in solution, but, unlike most complex acids, it can also crystallize as a tetrahydrate.

The structure of the title compound is made up of corrugated anionic layers of formula [BaCr(C2O4)3(H2O)3]nn– that leave voids accommodating the charge-compensating cations, [Ni(H2O)6]2+ (point group symmetry 
), as well as the water molecules of crystallization.

The single-crystal X-ray structure of [(18-crown-6)K][SnPh3(ox)] (ox = C2O42−) is reported. Integrity between neighboring molecules in the solid state is maintained by an array of C—H
O hydrogen bonds and C—Hπ interactions.

The title compounds are two closely related oxalate-bridged dinuclear copper complexes. The histamine ligand is in a gauche conformation and coordinates to copper ions in a bidentate chelating fashion. The dinuclear complexes are linked to form three-dimensional networks via different types of hydrogen-bond and weak interactions.

The structures of two new coordination polymers, ACr(C2O4)2(H2O)4, with A = Li (C2/m) and Na (P
), consist of alkali metal and Cr octahedra μ2-bridged by oxalate ligands. The resulting one-dimensional chains are connected together through hydrogen-bond motifs, leading to two-dimensional frameworks. However, they differ in the crystal packing, the hydrogen-bond networks and the oxygen disorder in the former polymer.

[Co(en)3][Co(ox)3]·5H2O shows stereoselective hydrogen-bonding interactions depending on the axis of interaction of [Co(en)3]3+. This has implications for chiral discriminations in solution.
