	<span style="line-height:1.5;">Uv-visible and fluorescence
spectra of the ligand 1,3-bis(2,2ĄŻ:6ĄŻ,2ĄŻĄŻ-ter- pyridyl-5-ymethylsulfanyl)propane </span><b style="line-height:1.5;">L</b><span style="line-height:1.5;"> and itĄŻs iron(II) complex have been investigated for
analytical purposes. The two spectra of L and terpy are very similar which
confirmed the ability of L to co-ordinate through the six N atoms of L with
minimum distortion of the metal ionĄŻs octahedral geometry. The ligand-based
absorption band of L is shifted to t</span><span style="line-height:1.5;">he longer wavelength. It was found that </span><b style="line-height:1.5;">L</b><span style="line-height:1.5;"> is able to displace the two terpyridine groups in the complex to give [FeL]</span><sup>2 </sup><span style="line-height:1.5;">.
The high stability of the complex makes it good in spectrophotometry
analysis of metals ions in solution. The fluorescence of </span><b style="line-height:1.5;">L</b><span style="line-height:1.5;"> was progressively
quenched with an increasing concentration of iron(II). This makes </span><b style="line-height:1.5;">L</b><span style="line-height:1.5;"> a
possible reagent for the quantitative analysis of metal by measuring fluorescence
quenching.</span>
