A new complex of formula [Co(nitmpy)2(tp)(H2O)2]n (nitmpy = 2-(3-pyridyl)- 4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide and tp = terephthalato dianion) has been synthesized and structurally characterized. The complex crystallizes in monoclinic, space group P21/n with a = 10.647(3), b = 11.093(3), c = 16.647(5) ? b = 106.185(6), V = 1888.2(10) 3, C32H40CoN6O10, Mr = 727.63, Dc = 1.280 g/cm3, m(MoKa) = 0.513 mm-1, F(000) = 762, Z = 2, the final R = 0.0549 and wR = 0.1265 for 1753 observed reflections (I > 2s(I)). The crystal structure consists of neutral infinite chains where the Co(nitmpy)2(H2O)2 units are linked by terephthalate ligands, and the 1-D chains develop into two-dimensional network via the hydrogen bond interactions.
