Synthesis, structure and physical properties of a low dimensional compound 2017 Access copy available to the general public Unrestricted The crystal structure of (µ3-oxo)hexakis(cyanoacetato-¿O, O')(cyanoacetato-¿O)diaquatriiron(III) cyanoacetic acid shows the formation of trinuclear complexes in a hydrogen-bond network that bonds all the molecules in a 3D arrangement. For this complex, within whose clusters the whole magnetic interaction takes place, 57Fe Mössbauer spectroscopy shows that the Fe cations are in the S = 5/2 state in the temperature range 2–295 K. The asymmetric broadening of the absorption peaks below 80 K is consistent with strong antiferromagnetic interactions between the metal spins. The magnetization measurements also show the antiferromagnetic character of the spin ensemble and an ST = 1/2 magnetic ground state typical of triangular systems with similar J between Fe-Fe pairs. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.88 2017 SPECTROSCOPY 7 / 42 = 0.167 2017 Q1 T1 0.648 2017 Instrumentation 2017 Q1 Spectroscopy 2017 Q2 Analytical Chemistry 2017 Q2 Atomic and Molecular Physics, and Optics 2017 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Coutinho, J.
