In the title compound, [Co(C(10)H(7)N(2)O(2))(2)(H(2)O)(4)], the Co(II) atom lies on an inversion centre and displays a slightly distorted octa-hedral geometry. The coordination sphere is defined by two mutually trans N atoms from two 4-(imidazol-1-yl)benzoate ligands and the O atoms from four water mol-ecules. The crystal structure is stabilized by O-H⋯O hydrogen bonds.

The reaction of CoCl with succinic acid and isonicotinamide in basic solution produces the title complex [Co(CHNO)(HO)](CHO). The cobalt(II) ion of the complex cation and the succinate anion are each located on an inversion centre. The Co ion is octa-hedrally coordinated by four O atoms of water mol-ecules and two N atoms of isonicotinamide mol-ecules.

The reaction of cobalt(II) with fumaric acid (Hfum) and isonicotinamide in a basic solution produces the title salt, [Co(CHNO)(HO)](CHO). In the complex cation, the Co atom, located on an inversion centre, is coordinated by two isonicotinamide and four water mol-ecules in a distorted NO octa-hedral geometry. The fumarate anion is located on another inversion centre and is linked to neighbouring complex cations O-H⋯O and N-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds.

In the structure of the title compound [systematic name: tetra-aqua-bis-(thio-cyanato-κ)cobalt(II)-1,3,7-trimethyl-1,2,3,6-tetra-hydro-7-purine-2,6-dione-water (1/2/4)], [Co(NCS)(HO)]·2CHNO·4HO, the cobalt(II) cation lies on an inversion centre and is coordinated in a slightly distorted octa-hedral geometry by the oxygen atoms of four water mol-ecules and two N atoms of two -arranged thio-cyanate anions. In the crystal, the complex mol-ecules inter-act with the caffeine mol-ecules through O-H⋯N, O-H⋯O and C-H⋯S hydrogen bonds and π-π inter-actions [centroid-to-centroid distance = 3.4715 (5) Å], forming layers parallel to the plane, which are further connected into a three-dimensional network by O-H⋯O and O-H⋯S hydrogen bonds involving the non-coordinating water mol-ecules.

The mol-ecule of the title compound, [Co(C8H6NO4)2(H2O)4], is centrosymmetric. It is a cobalt(II) complex, bearing two (2-nitro-phen-yl)acetate and four aqua ligands. The coordination around the Co(II) atom is distorted octa-hedral, defined by four O atoms of water mol-ecules in the equatorial plane and by two carboxyl-ate O atoms at axial positions.
