Three new MnII-benzoates coordination polymers containing various bipyridyl ligands (3,3′-dipicoylamine (3), 3-methylisoquinoline (4), and 4,4′-dithiopyridine (5)) and a [Mn6(O2CPh)10(μ4-OH)2(CH3OH)3(H2O)]·1.5(C4H4N2) cluster (1) have prepared and their structures were determined. The bipyridyl ligands can act as bridging ligands to produce 1-D or 2-D polymeric compounds. The pyrazine produced a Mn6 cluster molecule, and 3-methylisoquinoline did a benzoate-bridged 1-D MnII compound. The Mn6 cluster (1) and 1-D MnII compounds (3) and (4) show antiferromagnetic property. The compounds 1, 3, and 4 have catalyzed efficiently the transesterification of a variety of esters, while 5 has displayed a very slow conversion. The thermal stabilities of these complexes were also examined.
Three new MnII-benzoates coordination polymers containing various bipyridyl ligands (3,3′-dpicam, 3-methylisoquinoline, and 4,4′-dtp) and a [Mn6] cluster have prepared and characterized, and their magnetic property, thermal stabilities, and catalytic reactivity were discussed.Figure optionsDownload as PowerPoint slideHighlights
