Abstract

Three new Mn II-benzoates coordination polymers containing various bipyridyl ligands (3,3′-dipicoylamine (3), 3-methylisoquinoline (4), and 4,4′-dithiopyridine (5)) and a [Mn 6(O 2CPh) 104-OH) 2(CH 3OH) 3(H 2O)]·1.5(C 4H 4N 2) 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 Mn 6 cluster molecule, and 3-methylisoquinoline did a benzoate-bridged 1-D Mn II compound. The Mn 6 cluster (1) and 1-D Mn II 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.
