| dc.description.abstractEn | [Cu(hyetrz)3](CF3SO3)2·H2O [hyetrz = 4-(2-hydroxyethyl)-1,2,4-triazole] represents the first structurally characterised ferromagnetically coupled CuII chain compound containing triple N1,N2-1,2,4-triazole bridges. catena-[-Tris{4-(2-hydroxyethyl)-1,2,4-triazole-N1,N2}copper(II)] bis(trifluoromethanesulfonate) hydrate (C14H23F6S2O10CuN9) crystallises in the triclinic space group P , a = 13.54(3), b = 14.37(3), c = 15.61(4) Å, = 95.9(1), = 104.9(1), = 106.5(1)°, V = 2763(11) Å3, Z = 4 (CuII units). The CuII ions are linked by triple N1,N2-1,2,4-triazole bridges yielding an alternating chain with Cu1-Cu2 = 3.8842(4) Å and Cu2-Cu3 = 3.9354(4) Å. Analysis of the magnetic data according to a high-temperature series expansion gives a J value of +1.45(3) cm-1. The nature and the magnitude of the ferromagnetic exchange have been discussed on the basis of the structural features. | |
