- Abstract
- Three new polymeric compounds with general formula {[Gd(phen)(H2O)(3)Gd(phen)(H2O)(2)(mu-OH)(2)] [Re(4)Q(4)(CN)(12)]}.nH(2)O (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 [Re(4)Q(4)(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)(3)Gd(phen)(H2O)(2)(mu-OH)(2))](4-) connected through 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. (C) 2016 Elsevier Ltd. All rights reserved.
