Abstract
AbstractThree new one‐dimensional (1D) chain metal–nitroxide complexes {[Cu(NIT4Py)2(suc)(H2O)]·3H2O}n (1), {[Cd(NIT4Py)2(suc)(H2O)]·[Cd(NIT4Py)2(suc)(H2O)2]·3H2O}n (2), and {[Zn(NIT4Py)(glu)(H2O)]·H2O}n (3) [NIT4Py = 2‐(4′‐pyridyl)‐4, 4, 5, 5‐tetramethylimidazoline‐1‐oxyl‐3‐oxide, suc = succinate anion and glu = glutarate anion] were synthesized and structurally characterized. Single‐crystal X‐ray analyses indicate that the three complexes crystallize in neutral 1D chains in which the metal‐nitroxide units are linked by flexible dicarboxylate anions. The succinate anions only adopt trans configuration in complexes 1 and 2, whereas the glutarate anion has gauche/anti conformation in complex 3. Magnetic measurements show that complex 1 exhibits weak antiferromagnetic interactions between the copper ions and the nitroxides.
