The reaction of ammonium pyrrolidinedithiocarbamate,[NH4 {S2CN (CH2) 4}], with SnCl2,[Sn (C6H5) 2Cl2],[Sn (C6H5) 3Cl],[Sn (C4H9) 2Cl2] and [Sn (C6H11) 3Cl] produced in good yield the compounds [Sn {S2CN (CH2) 4} 2Cl2](1),[Sn {S2CN (CH2) 4} 2Ph2](2),[Sn {S2CN (CH2) 4} Ph3](3),[Sn {S2CN (CH2) 4} 2n-Bu2](4) and [Sn {S2CN (CH2) 4} Cy3](5). The complexes were characterised by infrared, multinuclear NMR (1H, 13C {1H} and ...
