Reaction medium pH dependent existence of MnII bound [ON] donor zwitterionic chelating ligand and self-assembly of hydroxido-bridged Mn 4IIcluster

A mononuclear MnN4O2 complex with two zwitterionic ligands and a centrosymmetric tetranuclear μ3-OH-bridged self-assembled Mn4 cluster were synthesized and characterized by using the [NO(H)N] ligand Hophbip [2,6-bis(phenylmethyliminomethyl)-4- methylphenol], The reaction, in MeOH in the presence of NH4SCN and a lower stoichiometry of Mn(OAc)2H2O without any added base produces [MnII(HNbip)2(NCS)2] ·CH3CN (1·CH3CN). In the presence of NaOH and NH 4SCN in MeOH, the cluster [Mn4II(μ-bip) 2(μ3-OH)2(NCS)4] (2), featuring a stepped-cubane, was obtained through, hydroxido-brid.ge-driven hydroxido-bridge-driven dimerization of two μ3-OHbridged [Mn 2] fragments derived from. 1-CH3CN.

Newμ4-oxido-bridged copper benzoate quasi-tetrahedron and bis-μ3-hydroxido-bridged copper azide and copper thiocyanate stepped cubanes: Core conversion, structural diversity, and magnetic properties

[Cu2(μ4-O)Cu2] and [Cu 2(μ3-OH)2Cu2] geometrical arrangements are found in a new family of tetranuclear complexes: [Cu 4(μ4-O)(μ-bip)2(μ-O2CPh) 4]· 0.5CH2Cl2 (1 -0.5CH 2Cl2), [Cu4(μ3-OH) 2(μ-bip)2(N3)4] (2), and [Cu 4- (μ3-OH)2(μ-bip)2(NCS) 4(DMF)2] (3·2DMF) [Hbip = 2,6- bis(benzyliminomethyl)-4-methylphenol; DMF = dimethylformamide]. These complexes have been characterized by X-ray crystallography, and their magnetic properties have been studied. Complex 1 reacts with azide and thiocyanate anions, leading to 2 and 3 with a change of the [Cu4(μ4-O)] core into [Cu4(μ3-OH)2] units. These compounds are new examples of [Cu4] complexes where CuII ions are connected by two types of water-derived ligands: oxide and hydroxide. Formation of these [Cu4] complexes can be controlled by changing the bridging ligands, which allows an effective tuning of the self-assembly. The study of the magnetic properties reveals that these complexes exhibit strong intramolecular antiferromagnetic interactions to yield a ST = O ground state. For the three complexes, the temperature dependence of the magnetic susceptibility was fitted using a model with two isolated S = 1/2 dimers based on the H = -2J{Scu,1·Scu,2} spin Hamiltonian with J/k B = -289 K for 1; J/kB = -464 and -405 K for 2 and 3, respectively (where J is the exchange constant through the oxido-phenoxido or hydroxido-phenoxido bridges, respectively).

Radical pathway in catecholase activity with zinc-based model complexes of compartmental ligands

Four dinuclear and three mononuclear ZnII complexes of phenol-based compartmental ligands (HL1-HL7) have been synthesized with the aim to investigate the viability of a radical pathway in catecholase activity. The complexe
