Addition of 2,2′-bipyridine (bpy), 1,10-phenanthroline (phen) or 2-aminopyridine (2-NH₂-py) to aqueous solutions of (NH₄)[NbO(C₂O₄)₂(H₂O)₂]·3H₂O (Nb-Ox) yields tris-oxalate complexes (bpyH₂)(bpyH)[NbO(C₂O₄)₃]·2H₂O (1), (phenH)₃[NbO(C₂O₄)₃]·3H₂O (2), and (2-NH₂-pyH)₃[NbO(C₂O₄)₃]·2H₂O (3), which were characterised by XRD, IR and EA. Bipyridinium salt 1 demonstrates remarkable photoactivity even under irradiation by daylight. The nature of the photoactivity was studied by diffuse reflectance (DR) spectroscopy, ESR and quantum-chemical calculations.
