摘要：

A new metal-organic framework of [Mn-4(L)(2)(4,4'-bipy)(2)(H2O)(4)]center dot(H2O)(4,4'-bipy)] (1) has been synthesized using a symmetrical tetracarboxylate 5-[bis(4-carboxybenzyl)-amino] isophthalic acid (H4L) and 4,4'-bipyridine (4,4'-bipy) coligands. The single crystal X-ray diffraction study indicates that in 1, the Mn(II) centers are bridged by L4- and 4,4'-bipy ligands to furnish a 3D framework with a rare (4,6,6)-connected (4.5(3).6(2))(2)(4(2).5(4).6(6).7(2).8} {5(7).6(6).8(2)} topology. 1 exhibits related lower photocatalytic activity for degradation of organic dye methyl violet (MV) under UV light and offers good stability after performing photocatalysis. A mechanism for the photcatalytic property of MOF is proposed, which is based on the results of density of states (DOS) and partial DOS calculations.
