On February 28, 2011, Kato, Masaru; Hida, Kazuo; Fujihara, Takashi; Nagasawa, Akira published an article.Product Details of 26172-54-3 The title of the article was Ferromagnetic Spin Ladder System: Stack of Chlorido-Bridged Dinuclear Copper(II) Complexes with 2-Methylisothiazol-3(2H)-one. And the article contained the following:

A dinuclear copper(II) complex, [{CuIICl(O-mi)}2(μ-Cl)2] [mi = 2-methylisothiazol-3(2H)-one], has been synthesized and its mol. structure in the solid state determined by single-crystal X-ray anal. The crystal consists of centrosym. dinuclear copper(II) units in which each copper(II) ion is doubly bridged by two chloride ions and has a slightly distorted square-planar geometry with a terminal chlorido ligand and a terminal mi ligand coordinated through the oxygen atom. The dinuclear units stack one on top of another to form a one-dimensional two-leg ladder structure. The magnetic susceptibility of the powder was measured in the temperature range 3.0-302 K. It was found that there are ferromagnetic interactions along the rung (in the same direction of the intramol.; Jrung = +5.03 ± 0.03 cm-1) and the leg (in the same direction of the intermol.; Jleg = +1.96 ± 0.02 cm-1) and an antiferromagnetic interaction along the diagonal (Jx = -1.36 ± 0.02 cm-1), the exptl. data being fitted by the numerical calculation for a twelve-site ladder Hamiltonian. In addition, DFT calculations with the UB3LYP functional on the model complex [{CuIICl(O-mi)}2(μ-Cl)2] gave an intramol. magnetic coupling constant J = +28.6 cm-1 and indicated that the spin-d. distribution on O in mi is less than that on the terminal Cl. We conclude that the O-donor ligand at the terminal position plays an essential role in the emerging intramol. ferromagnetic interaction. The experimental process involved the reaction of 2-Methylisothiazol-3(2H)-one hydrochloride(cas: 26172-54-3).Product Details of 26172-54-3
