Abstract
The title complex, (C7H6N2)3(C4H5NO4)Co·2H2O, has been prepared and its crystal structure determined by single-crystal X-ray diffraction methods. The cobalt atom is octahedrally coordinated by three benzimidazole molecules and an iminodiacetate anion. The anion coordinates facially as a tridentate. Extensive intermolecular hydrogen bonding and C−H· · ·π interactions occur in the crystal. Thermal decomposition of the complex has been studied by thermogravimetry and differential scanning calorimetry. The IR spectral assignments were based on the molecular structure.
