Co(II)-Based single-ion magnets with 1,1 '-ferrocenediyl-bis(diphenylphosphine) metalloligands
Hrubý, Jakub; Dvořák, Dalibor; Squillantini, Lorenzo; Mannini, Mateo; van Slageren, Joris; Herchel, Radovan; Nemec, Ivan; Neugebauer, Petr (Royal Society of Chemistry, 2020-09-07)Herein, we report on investigations of magnetic and spectroscopic properties of three heterobimetallic Fe(ii)-Co(ii) coordination compounds based on the tetracoordinate {CoP2X2} core encapsulated by dppf metalloligand, ... -
Deposition of Tetracoordinate Co(II) Complex with Chalcone Ligands on Graphene
Hrubý, Jakub; Vavrečková, Šárka; Masaryk, Lukáš; Sojka, Antonín; Navarro Giraldo, Jorge Andres; Bartoš, Miroslav; Herchel, Radovan; Moncol, Ján; Nemec, Ivan; Neugebauer, Petr (MDPI, 2020-11-01)Studying the properties of complex molecules on surfaces is still mostly an unexplored research area because the deposition of the metal complexes has many pitfalls. Herein, we probed the possibility to produce surface ... -

A new series of Schiff base Ni(II)4 cubanes: Evaluation of magnetic coupling via carboxylate bridges.
Gusev, Alexey; Nemec, Ivan; Herchel, Radovan; Baluda, Yuriy; Maria, Kryukova; Yefimov, Nikolay; Kiskin, Mikhail; Linert, Wolfgang (Elsevier, 2021-01-02)The Schiff base ligand H2L has been synthesized by condensation of 2-aminophenol with 3-methyl-1-phenyl-4-formylpyrazol-5-one and reaction between H2L and Ni(OOCR3)2, R = H in 1, –CH3 in 2, Cl in 3, yielded three new ... -
Periferní funkcionalizace polydentátních Schiffových ligandů pro přípravu biologicky aktivních komplexů Fe(III) a Co(III)
Kotásková, LucieDiplomová práce se zabývá přípravou periferně funkcionalizovanými polydentátními Schiffovými ligandy, vhodnými pro koordinaci kovů, jakými jsou Fe(III) nebo Co(III). Sloučeniny, vzniklé touto funkcionalizací za použití ... -
Spin Crossover in Three Mononuclear Iron (III) Schiff Base Complexes
Nemec, Ivan; Svoboda, Ingrid; Herchel, Radovan (MDPI, 2019-08-02)The synthesis, crystal structure, and magnetic properties of three new mononuclear complexes [Fe(R-LA)(L1)](BPh4), where R-LA(2-) is a doubly deprotonated pentadentate Schiff base ligand and L1 is a monodentate benzimidazole ...
