Three new chlorodiorganotin(IV) methylferrocenyl dithiocarbamate complexes viz. [(FcCH(2))(CH(2)CH2OH) NCS2SnMe2(Cl)] (1), [(FcCH(2))(CH2CH2OH)(NCS2SnBu2)-Bu-n(Cl)] (2) and [(FcCH(2))(CH2CH2OH)NCS2SnPh(2)(Cl)] (3) have been synthesized and characterized by elemental analysis, IR, UV-Vis, H-1, C-13 and Sn-119 NMR spectroscopy and X-ray crystallography. The crystal structure of 1 indicates that the coordination geometries around the tin(IV) center is intermediate between ideal trigonal-bipyramidal and square pyramidal coordination polyhedra bonded through two sulfur atoms of the dithiocarbamate ligand in an isobidentate mode, two CH3 groups and one chlorine atom. Since, in 2 and 3 only alkyl and aryl fragments have been changed we infer that both 2 and 3 would also have the same behaviors in the solution state as observed in 1. Ionic interactions abilities of 1-3 are examined in acetonitrile through UV-vis absorption spectroscopy which offers reasonably good selectivity and sensitivity towards the detection of the acetate ion. Compounds 1 3 exhibit a bathochromic shift with the acetate ion with a moderate association constant.
