A new complex {[Cu(NIT4py)2(ip)]?6H2O}n (NIT4py=2-(4′-pyridinyl)-4,4,5,5-tetra methylimidazoline-1-oxyl-3-oxide and ip = isophthalate dianion) has been synthesized and structu- rally characterized by X-ray diffraction. It crystallizes in orthorhombic, space group Cmcm with a = 25.161(3), b =10.045(1), c = 15.450(2) ?, C32H48N6O14Cu, Mr = 804.30, V = 3904.8(8) ?3, Z = 4, Dc = 1.368 g/cm3, μ(MoKα) = 0.630 mm?1, F(000) = 1692, the final R = 0.0326 and wR = 0.0787 for 1843 independent reflections with Rint = 0.0372. Each Cu(II) ion is four-coordinated by two car- boxylate oxygen atoms and two pyridyl-N atoms from NIT4py radicals to furnish a rhombus geometry. The central Cu(II) ion is located at an inversion center and a crystallographic two-fold axis. Each isophthalate dianion binds two Cu(II) ions in bis-monodentate mode, leading to a 1-D chain, and these 1-D chains are further linked into a 2-D network via hydrogen-bonding interac- tions.
