摘要：

A new trinuclear complex Mn-3(2,2'-bipy)(2)(C7H5O3)(6) (1) with alpha-furacrylic acid (HL) and 2,2'-bipyridine as ligands has been synthesized. In 1, six L- anions link three Mn(II) cations to form a trinuclear structure. Each Mn cation is coordinated by six atoms to give a distorted octahedral coordination geometry. The luminescence and electrochemical properties of 1 were investigated. Complex 1 exhibits one intense fluorescence emission band at around 498 nm. It is paramagnetic showing weak antiferromagnetic coupling at low temperature. The electron transfer is irreversible in the electrode reaction of 1, one electron being involved in the reduction corresponding to Mn(III)/Mn(II).
