Crystal structure and characterization of new binuclear manganese (Ⅱ)complex based on polyaza imino macrocyclic ligand
摘要
Abstract
With the aim of finding the best conditions for the synthesis of binuclear macrocyclic complexes by the template reaction and better understanding their structures,the title compound,a new binuclear manganese (II) complex based on a polyaza imino macrocyclic ligand was prepared by [2+2] template condensation of 1,3-diaminopropane with 2,6-diformyl-4-methylphenol in the presence of manganese(II) chloride,and characterized by infrared spectra,and electrospray mass spectra.Its crystal and molecular structure was determined by X-ray diffraction methods.The crystal crystallizes in the monoclinic system,space group P2 (1)/c with a =0.749 44(8) nm,b=1.045 84(11) nm,c=1.636 57(18) nm,β3 =93.854(2)~,Mr =583.27,V =1.279 8(2) nm3,Z =2,Dc =1.514 g/cm3,F(000) =596,R =0.039 7 and wR =0.111 2.The complex is composed of a di-hydrogen deposed polyaza imino macrocyclic ligand,two manganese (II) ions and two chlorides.Each manganese ion is located in one of the two compartments of the macrocyclic ligand and five-coordinated in a square pyramidal geometry in which two oxygen and two nitrogen atoms of macrocycle build the basal plane of the pyramid,and the chloride ion is located at the top of the pyramid.Study of X-ray diffraction methods and electrospraymass spectrometry confirms that the binuclear entity exists in the complex and the title complex is very stable.关键词
