| Abstract: | A novel three-dimensional cobalt(II)-radical complex {Co(NITmPy)2N(CN)2]2}n (NITmPy = 2-(3′-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) is prepared and characterized by X-ray crystallography. The complex crystallizes in the monoclinic system, space group P21/c, with unit cell parameters a = 12.5775(5) Å, b = 10.9340(5) Å, c = 11.6134(5) Å, β = 108.1320(10)°; V = 1517.79(11) Å3, ρcalcd = 1.443 g/cm3, and Z = 2 for R 1 = 0.0463. In the complex, each cobalt ion is six-coordinate with four nitrogen atoms from four N(CN) 2 t- ligands and two nitrogen atoms of pyridyl groups, and the Co(NITmPy)2]2+ units are linked by N(CN) 2 t- μ-bridging ligands to form a three-dimensional structure. The variable-temperature magnetic susceptibility data show that the complex exhibits weak antiferromagnetic interactions. |
