Five coordination compounds based on a new ligand with terpyridyl and benzenesulfonyl groups, [Cd(STP)2]n (1), [Cd(STP)Cl(H2O)]n·2nH2O (2), [Cd(STP)Br(H2O)]n·2nH2O (3), [Co(STP)2]n (4), [Co(STP)2(H2O)4]·H2O (5) (HSTP = 2-(3,2′:6′,3”-terpyridin-4′-yl)benzenesulfonic acid) were synthesized and characterized by FT-IR, elemental anal., and single crystal X-ray diffraction. Compounds 1 and 4 exhibit a (3,6)-connected 2D layer structure with 3,6L40 topol. network and point symbol of {3·62}{66·96·123}. Compounds 2 and 3 display a 3D topol. network with fsc-3 network and point symbol of {4·6·8}{4·62·83}. Compound 5 shows a discrete mononuclear structure. The structural diversity of compounds 1-5 indicates that counter anions, pH values and coordination modes of STP- anions are significant influence on the final structures. Investigation of luminescent property indicates that compound 3 can be used as a recycled probe with high sensitivity and selectivity to detect acetone and Cr2O72- anion. The KSV of compound 3 for acetone and Cr2O72- anion are 1.295 x 104 M-1 and 5.79 x 102 M-1, resp. The PXRD and UV-Vis spectra indicates that the quenching mechanism of compound 3 toward Cr2O72- anion can be attributed to light competitive absorption. Addnl., magnetic property of compounds 4 and 5 was investigated. The difference of magnetic interactions between compounds 4 and 5 may be caused by different coordination fields.
