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 NiII 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.
