Abstract: The reaction between the ligand di(4-pyridyl)sulfide (dps) and two salts of divalent first row transition metals (M = Co2+, and Cu2+) resulted in three new compounds with formula: [Co(dps)(4)(H2O)(2)](ClO4)(2)center dot H2O (1), [Cu(dps)(2)(dmso)(2)](n)(ClO4)(2n) (2) and...

Abstract: The reaction between the ligand di(4-pyridyl)sulfide (dps) and two salts of divalent first row transition metals (M = Co2+, and Cu2+) resulted in three new compounds with formula: [Co(dps)(4)(H2O)(2)](ClO4)(2)center dot H2O (1), [Cu(dps)(2)(dmso)(2)](n)(ClO4)(2n) (2) and [{Cu(dps)(2)(dmso)(2)}{Cu(dps)(2)(dmso)(H2O)}](n)(ClO4)(4n)center dot 2nH(2)O center dot n(dmso) (3). Crystal structures of 1-3 were determined using single-crystal X-ray diffraction. Crystal structure of 1 consists of a mononuclear complex, in which the dps ligand acts in a monodentate mode through one of the pyridyl nitrogen atoms. Compounds 2 and 3 present the dps ligands bridging metal centers leading to bidimensional coordination polymers. Magnetic properties in the polycrystalline samples of 1-3 in the 300-2 K temperature range were investigated. Complex 1 exhibits a field-induced slow magnetization behavior and behaves as a single-ion magnet with an effective energy barrier for the reversal of magnetization of 22.9 (1.1) K and tau(0) = 5.3(1.2) x 10(-7) s
