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) ₁₀(μ ₄-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.
