In the crystal structure of the title compound, C6H7N·CH4N2O, the 2-methylpyridine and urea molecules are linked via N—HO and N—HN hydrogen bonds, forming ribbons extending along the a axis. The dihedral angle between the 2-methylpyridine and urea mean planes is 89.09 (9)°. The methyl group shows rotational disorder wherein the H atoms are located over two sets of sites with equal occupancies.

In the title compound, [Ni(C8H6ClO3)2(H2O)4], the NiII ion is located on a crystallographic inversion centre and is octahedrally coordinated by two 2-(4-chlorophenoxy)acetate ligands in axial positions and by four water molecules in the equatorial plane. The acetate ligands are bound to the NiII ion in a monodentate manner through a carboxylate O atom. In the crystal, O—HO hydrogen bonds link the molecules, forming a two-dimensional supramolecular network lying parallel to the ab plane.
