In the title complex, [Co(NCS) 2(C 3H 4N 2) 2(C 11H 6N 2O)], the Co II atom has a distorted octahedral coordination with the N atoms of the 4,5-diazafluoren-9-one ligand and two N atoms from imidazole ligands in the equatorial positions and the axial sites occupied by two N atoms of the thiocyanate ligand. Intermolecular N - H⋯O hydrogen bonding forms a onedimensional motif parallel to the cell ab diagonal.

In the title compound, [Co(C 12H 11N 2O 4) 2(H 2O) 4]·4H 2O, the Co II atom lies on an inversion center and is octahedrally coordinated by six O atoms from four water molecules and two monodentate zwitterionic 2-methylbenzimidazolium-1,3-diacetate ligands. An intramolecular O - H⋯O hydrogen bond occurs. In the crystal, intermolecular O - H⋯O hydrogen bonds link the molecules into a threedimensional network. π-π interactions between the imidazole and benzene rings [centroidcentroid distance = 3.9031 (17) Å] consolidate the crystal packing.

In the title complex, [Co(NCS)2(C8H 9NO2)4], the CoII atom is six-coordinated by four N atoms from four ethyl pyridine-4-carboxylate ligands in the equatorial plane and two N atoms of thio-cyanate ligands in the axial positions, showing a slightly distorted octahedral geometry. The structure exhibits disorder in one of the ethyl chains, which was refined using a two-site model with 0.70 (6):0.30 (6) occupancy.

In the title compound, [Co(C8H6N3) 2(C2H8N2)]NO3· H2O, the CoIII ion is coordinated by four N atoms from two 2-(pyridin-2-yl)-1,3-imidazol-1-ide ligands and two N atoms of ethyl-enediamine in a distorted octahedral geometry. In the crystal, classical N - H⋯N(O) and O - H⋯N(O) hydrogen bonds connect all the isolated components together to yield a three-dimensional structure.
