A series of new mononuclear octahedral nickel(II) complexes with the Ni(N∩N)xL2 framework (x = 2 or 3, N∩N = Рhen (1,10-phenanthroline), AMPy (2-(aminomethyl)pyridine), L is H2O, anions of carboxylic acids (CF3CO2−, CCl3CO2−, HCO2−), chloride ion, and water) is synthesized and described by IR spectroscopy, mass spectrometry, elemental analysis, and X-ray diffraction analysis: [Ni(Рhen)2(OH2)Cl]Cl · 2H2O (I), [Ni(Рhen)2(OH2)(O2CCF3)](O2CCF3) (II, IIa), [Ni(Рhen)2(HCOO)1.618(H2O)0.382](HCOO)0.382 · 4.618H2O (III), ([Ni(Рhen)2(OH2)2](O2CCCl3)2 · 6.2H2O (IV), [Ni(AMPy)2(OH2)2](HCO2)2 · 6H2O (V), and [Ni(Рhen)3](CCl3COO)2 · 7H2O (VI). The subunit containing two formate ligands in the inner sphere of the [Ni(Рhen)2(HCO2)2] complex prevails in the crystal structure of complex III, which is not characteristic of the nickel carboxylate complexes of this type. In aqueous solutions complex IV undergoes decarboxylation to form [Ni(Рhen)2(CO3)] · 7H2O. A change in the nature of the N-donor ligands in Ni(N∩N)2L2 leads to the change (cis or trans) in the configuration of the whole complex (СIF files CCDC no. 880414 (I), 842336 (II), 1430414 (IIa), 1478111 (III), 1430430 (IV), 1443133 (V), and 1430415 (VI)).
