New Magnetic and Structural Results for Uniformly Spaced, Alternatingly Spaced, and Ladder-Like Copper(II) Linear Chain Compounds.

Abstract

Results of recent synthetic, structural, and magnetic work on exchange coupled copper (II) ions bridged by nonmagnetic ligands are discussed, including the quasi-linear chain compound bis(dimethyldithiocarbamato)copper(II) in which the copper(II) ions are antiferromagnetically exchange coupled. An unusual correlation exist in the structural and magnetic data for (Cu(dmtc)2) infinity and other known sulfur bridged copper compounds. Data are presented for the alternatingly spaced linear chain compounds di-mu-chlorobis-(4-methylpyridin e)copper (II), and a series of dionebis(thiosemicarbazato)copper(II) compounds. Exchange coupling constants and alternation parameters were obtained from expressions which were empirically generated from calculations on rings of ten S = 1/2 ions for kT (absolute value of J) approx = or > 0.5 and J < 0. Finally, New results for recently discovered spin ladder systems are presented. (Author)
