Synthesis, structure, magnetic properties and DFT calculations of two hydroxo-bridged complexes based on MnIII(Schiff-Bases)†
Abstract
Two hydroxo-bridged complexes, {[MnIII(3-CH3O)salen]2[CrIII(salen)(OH)2]}ClO4·6H2O (1) and {[MnIII(5-CH3)salen]2(OH)}ClO4·3H2O (2) [salen = N,N′-ethylenebis(salicylideneiminato) dianion], have been synthesized by the hydrolysis of the corresponding MnIII(Schiff-Bases) derivatives and [Cr(salen)(H2O)2]Cl precursors. X-Ray structure characterization reveals the discrete linear arched trinuclear structure of 1 and the 1D chain arrangement of 2. Magnetic
