Abstract: The hydrothermal reaction of Ni₂(OH)₂CO₃ with 2,2'-bipyridine and 2-indolyl-formic acid in CH₃OH/H₂O at 423 K for 7 d produced the novel Ni^II complex [Ni(C₉H₆NO₂)(C₁₀H₈N₂)₂(H₂O)](C₉H₆NO₂)·2H₂O. The asymmetric unit of the title compound consists of a monovalent [Ni(L)(bpy)₂(H₂O)]⁺ cation (bpy is 2,2'-bipyridine and L is 1H-indole-2-carboxylate), an L anion and two solvent water molecules. In the [Ni(L)(bpy)₂(H₂O)]⁺ cations, the Ni atom coordinates to four N atoms from the two bpy ligands and two O atoms, one from a L anion and the other from a water molecule to complete an significantly distorted NiN₄O₂ octahedron. The coordinated and solvate water molecules form an extensive series of O-HO hydrogen bonds. N-HO and C-HO hydrogen bonds are also present and the molecules are interlinked, forming a three-dimensional network.
