Syntheses, structures, electrochemical measurements and magnetic properties of two iron(III) complexes derived from N,N′-o-phenylenebis(3-ethoxysalicylaldimine)
Abstract The work in this paper presents syntheses, characterizations, crystal structures, electrochemical measurements and magnetic properties of two iron(III) compounds [FeIIIL(H2O)(MeOH)](ClO4) (1) and [FeIIIL(H2O)2](NO3)·H2O (2) derived from the Schiff base compartmental ligand N,N′-o-phenylenebis(3-ethoxysalicylaldimine) (H2L). The two compounds are characterized by elemental analyses, IR, electrospray ionization mass (ESI-MS positive), UV–Vis spectra and conductance values. The structures of 1 and 2 show that these are mononuclear compounds having the metal ion in the N2O2 compartment. Two mononuclear moieties in both the compounds are self-assembled due to bifurcated hydrogen bonds i…
A Series of MIICuII3 Stars (M = Mn, Ni, Cu, Zn) Exhibiting Unusual Magnetic Properties
The work in this report describes the syntheses, electrospray ionization mass spectromtery, structures, and experimental and density functional theoretical (DFT) magnetic properties of four tetrametallic stars of composition [M(II)(Cu(II)L)3](ClO4)2 (1, M = Mn; 2, M = Ni; 3, M = Cu; 4, M = Zn) derived from a single-compartment Schiff base ligand, N,N'-bis(salicylidene)-1,4-butanediamine (H2L), which is the [2 + 1] condensation product of salicylaldehyde and 1,4-diaminobutane. The central metal ion (Mn(II), Ni(II), Cu(II), or Zn(II)) is linked with two μ2-phenoxo bridges of each of the three [Cu(II)L] moieties, and thus the central metal ion is encapsulated in between three [Cu(II)L] units. …
