Abstract
Three new polymeric compounds with general formula {[Gd(phen)(H2O)3Gd(phen)(H2O)2(μ-OH)2][Re4Q4(CN)12]}·nH2O (Q = S0.84Te0.16, n = 0.25 for compound 1; Q = Se, Te, n = 1 for compounds 2, 3, respectively) were obtained by self-assembly reaction of [Re4Q4(CN)12]4- cluster anions, Gd3+ cation and 1,10-phenthroline (phen) in a solvothermal conditions. Compounds were investigated by single-crystal X-ray diffraction, magnetic measurements and thermogravimetric analysis. Structure of compounds consist of non-charged ladder chains formed by alternating [Re4Q4(CN)12]4- cluster anions and dimeric cationic complex [{Gd(phen)(H2O)3Gd(phen)(H2O)2(μ-OH)2}]4+ connected through -CN-Gd-NC- covalent bonds. Chains are packed parallel and linked with each other by a system of hydrogen bonds. The magnetic susceptibility of compounds is determined by spins of Gd3+ ions that weakly antiferromagnetic coupled in dimeric cationic fragments.
