Synthesis,crystal structure and luminescent property of a novel H2O-bridged cobalt(II)polymer with one-dimensional chain structure

摘要

The coordination compound[Co(C10H7COO)2(H2O)3]_(2n)centre dot 4nH2O was prepared by the reaction of 1-naphthoic acid and cobalt(II)acetate tetrahydrate in basic solution,and was fully characterized by X-ray diffraction,element analysis,FTIR,TG-DTA and luminescent spectra.In the crystal the six-coordinated Co(II)centers are linked into one-dimensional zigzag chains by water molecules,which are further assembled into a two-dimensional network through weak inter-chain C-H…pi interactions.The solid complex exhibits favorable fluorescent properties similar to those of free ligand at room temperature,which can be assigned to the intraligand electronic transfer.
