dc.description.abstract © 2020 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim A new tert-buthylthiacalix[4]arene-based tetranuclear 3d-4f metal complex with the Mn2Tb2 core has been synthesized and its molecular and crystal structures have been studied by X-ray diffraction. The complex geometry is similar to that of the earlier synthesized tert-buthylthiacalix[4]arene-based M2Ln2 complexes with M=Mn(II), Co(II), and Ln=Gd, Pr, Eu, but unlike those systems, it exhibits intricated cooperative low-temperature magnetic properties arising from the presence of intercluster interactions. At T<8.5 K the complex shows weak spin-canted ferromagnetism and field induced metamagnetic phase transition. The paramagnetic behavior observed at temperatures higher than 8.5 K is similar to that previously reported for the Mn2Gd2 complex, this being indicative of the existence of competitive ferro- and antiferromagnetic intracluster interactions.
