Abstract: In the title cocrystal, [Ni(C₁₁H₁₀N₃O₂)₂]·[Ni(NCS)₂(C₁₁H₁₁N₃O₂)(H₂O)], both Ni^II ions are in disorted octahedral coordination environments. One Ni^II ion is coordinated by four N atoms and two O atoms from two tridentate 6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate (DPP) ligands, while the other Ni^II ion is coordinated by a tridentate 6-((3,5-dimethyl-1H-pyrazol-1-yl))picolinic acid (DPPH) ligand and by two N atoms and one O atom from two thiocyanate and one water ligand, respectively. In the crystal structure, molecules are linked by intermolecular O-HO and O-HS hydrogen bonds, forming extended chains along [010].
