一种新型双吡啶悬臂Mn(Ⅱ)配合物的合成、晶体结构及DNA结合能力研究
Synthesis, Crystal Structure, DNA Binding Ability of a New Bis-Pyridine Pendant-Arms Mn(Ⅱ) Complex
摘要
Abstract
A new dinuclear manganese(Ⅱ) complex with bis-pyridine pendant-arms was synthesized by condensation between 3,3′-((ethane-1,2-diylbis((pyridin-2-ylmethyl)azanediyl)) bis(methylene))bis(2-hydroxy-5-methylbenzaldehyde) and 2-hydroxy-1,3-diaminopropane in the presence of manganese(Ⅱ). The complex was determined by X-ray diffraction single crystal structure analysis, and the corresponding formula is [ Mn2 ( C37 H43 N6 O6 ) ] · ( ClO4 ) 2 . The results indicate that the complex crystallizes in monoclinic, space group P21/c, with a=1. 09650(19) nm, b=1. 4195(3) nm, c=3. 1094(5) nm,β=108. 153(5)°. The crystal structure shows that the two manganese(Ⅱ) ions in the phenolbased macrocyclic dinuclear complex are coordinated with (Namine)2(Nimine)2O3 and (Nimine)2O4 sites, the corresponding geometry around each manganese (Ⅱ) center are decahedron and distorted octahedron. Two manganese(Ⅱ) centers are equivalently bridged by the phenolic oxygens and an acetate radical with the intermetallic separation of 0. 3316 nm. Moreover, the binding ability of the complex toward calf thymus DNA were analyzed by voltammetric and viscosity method, which indicate the bonding mode between them is weak intercalation.关键词
