Synthesis,Crystal Structure and Fluorescent Property of the Dimeric Complex [Mn(1,6-nds)(phen)_2(H_2O)]_2·(CH_3OH)_3·(H_2O)_2

The dimeric Mn( Ⅱ) complex [Mn( 1,6-nds)( phen)2( H2O) ]2·( CH3OH)3·( H2O)2,( 1,6-nds = 1,6-naphthalene-disulfonate anion,phen = 1,10-phenanthroline) was synthesized by hydrothermal method. It was characterized by X-ray crystal diffraction,IR,thermogravimetric analysis, UV-Vis spectroscopy,etc. The characterization results of X-ray single crystal diffraction show that the crystal of the complex crystallized in triclinic system with space group P-1. The manganese anion coordinates with two 1,10-phenanthroline molecules, one water molecule and 1, 6-naphthalenedisulfonate anion to form [Mn( 1,6-nds)( phen)2( H2O) ]structural unit. The structural units,methanol and water molecules are interconnected through two kinds of hydrogen bonds O-H … O and O-H … S, forming a three-dimensional network structure. Compared with the ligands,the fluorescence spectrum happens red shift,and the maximum emission peak is at 439 nm.
