Description
  • Bylo provedeno srovnání strukturních, spektroskopických, elektrochemických a magnetických vlastností pyrazolátových a karboxylátových komplexů [Fe-3(mu(3)(mu O-3)(mu-LL)(6)Cl-3](2-), teré obsahují motiv Fe-3(mu(3)-O). Zatímco Fe-3(mu(3)-O)-uspořádání jsou strukturně nerozlišitelná u obou typů komplexů, jejich magnetické vlastnosti se liší z důvodu příspěvku pyrazolu k celkové antiferromagnetické interakci: J(1)/hc -80.1 cm(-1) a J(2)/hc = -72.4 cm(-1) nebo J(1)/hc = 70.6 cm(-1) and J(2)/hc = -80.8 cm(-1), (H-ex = -J(1)(S1S2 + S2S3) J(2)S(1)S(3)). Magnetické vlastnosti komplexů s pyrazolem jsou také odlišné z důvodu antisymetrické výměnné interakce. (cs)
  • A comparison is made between the structural, spectroscopic, electrochemical, and magnetic properties of pyrazolate versus carboxylate complexes [Fe-3(mu(3)(mu O-3)(mu-LL)(6)Cl-3](2-) containing the Fe-3(mu(3)-O)-motif. While the Fe-3(mu(3)-O)-cores are structurally indistinguishable in the two types of complexes, their magnetic properties deviate from the expected values as a result of a through-pyrazole contribution to the overall antiferromagnetic exchange with J(1)/hc -80.1 cm(-1) and J(2)/hc = -72.4 cm(-1), or J(1)/hc = 70.6 cm(-1) and J(2)/hc = -80.8 cm(-1), (H-ex = -J(1)(S1S2 + S2S3) J(2)S(1)S(3)). The magnetic properties of the pyrazolate complexes are further tuned by an antisymmetric exchange interaction term.
