The synthesis and characterization of [Cu(3-Me-2-tpc)(2)(nia)(2)] (1), [Cu(5-Me-2-tpc)(2)(nia)(2)] (2), [Cu(2-tpc)(2)(nia)(2)] (3) and [Cu(5-Me-2-tpc)(2)(nia)(2)(H2O)] (4) (where 2-tpc is 2-thiophenecarboxylate, 3-Me-2-tpc is 3-methyl-2-thiophenecarboxylate, 5-Me-2-tpc is 5-methyl-2-thiophenecarboxylate and nia is nicotinamide) are reported. The complexes under study were characterized by electronic, IR, EPR spectroscopy, magnetic susceptibility over the temperature range and X-ray structure analysis. The coordination arrangement around each copper(II) atom is a distorted tetragonal bipyramidal. The discrepancies between two Cu-O axial bond distances increases in the order: 0 angstrom (complex 1) { 0.050 angstrom (complex 3) { 0.209 angstrom (complex 2) { 0.516 angstrom (complex 4, Cu1) { 0.746 angstrom (complex 4, Cu2), indicating that in the same order a distortion of the respective tetragonal bipyramids increases. This is in a good agreement with the ligand field band position in th
