Synthesis, crystal structure and magnetic properties of three polynuclear manganese compounds bearing ferrocenecarboxylato ligands

“…Ferrocenecarboxylic acids, as ligands containing typical organometallic group that exhibits not only high thermal stability, but also excellent redox activity and attractive properties in respect of catalysis, magnetism and nonlinear optics [6], have attracted much interest in coordination chemistry in recent years. Some metal complexes with ferrocenecarboxylic acid ligand have been reported [7][8][9][10][11][12]. In this context, we have also reported recently two manganese complexes bearing ferrocenecarboxylato ligands [10].…”

“…The central Mn2 ion is coordinated in an octahedral geometry by six oxygen atoms from six ferrocenecarboxylato ligands with the O-Mn-O angle in the range of 85.49 (15) to 94.51(15) Å . The coordination of each terminal Mn(II) ion to two nitrogen atoms and four oxygen atoms from three ferrocenecarboxylato ligands leads to a distorted trigonal antiprism geometry with the O-Mn-N and O-Mn-O angles in the range of 56.31 (11) to 162.32 (14) Å .…”

“…Both of them exhibit a weak antiferromagnetic coupling between Mn(II) ions bridged by ferrocenecarboxylato ligand. To the best of our knowledge, only two cases of discrete polynuclear manganese complexes containing ferrocenecarboxylato ligands, that is, a dinuclear complex cation [Mn 2 (phen) 4 (FCA) 2 ] 2+ (FCA = anion of 3-ferrocenyl-2-crotonic acid) [8] and a manganese supercubane [Mn 13 O 8 (OCH 3 ) 6 (fcdc) 6 ] (fcdc = 1,1 0 -ferrocenedicarboxylate) [11], have been reported in the literatures, and no magnetic properties of discrete polynuclear manganeseferrocenecarboxylate complexes have ever been studied previously.…”

Synthesis, Crystal Structure, and Magnetic Properties of Two Manganese(II) Polymers Bearing Ferrocenecarboxylato Ligands

“…[8][9][10] Among them, only the study reported by Hou, et al includes some investigation of the magnetic properties of the manganese complex with a p-ferrocenylbenzoato ligand. [9] In the other two cases, Tian, et al [8] and Kondo et al [10] described the redox properties of a dinuclear complex cation [Mn 2 (phen) 4 …”

Luminescence and Electrochemical Properties of Organostannoxane Coordination Polymer Based on Ferrocenyl-2-Cyano Carboxylate Ligand

“…In general, organotin compounds are traditionally synthesized by the use of high boiling solvents under reflux conditions and the structural diversity is depends on the reaction conditions [10,11]. In this study, we used simple one pot reaction between organotin (nBu3Sn)2O precursor and 2-cyano-3-ferrocenyl acrylic acid which leads polymeric compound.…”
