✦ Synopsis

Some new diorganotin(IV) complexes of heterocyclic dithiocarbamate having general formula R 2 Sn(Cl)S 2 CNR 2 and R 2 Sn(S 2 CNR 2 ) 2 [R = 2-F-Bz, 3-Cl-Bz; NR 2 = N(CH 2 CH 2 ) 2 NMe, N(CH 2 CH 2 ) 2 NEt, and N(CH 2 CH 2 ) 2 NBz] have been prepared, respectively. Elemental analyses, IR, and NMR spectral data characterized all compounds. The crystal structures of (2-F-Bz) 2 Sn(Cl)S 2 CN(CH 2 CH 2 ) 2 NEt 2 and (3-Cl-Bz) 2 Sn[S 2 CN(CH 2 CH 2 ) 2 NEt] 2 •0.5 HN(CH 2 CH 2 ) 2 NH 5 were determined by single crystal X-ray diffractometer. In the crystal of complex 2, the tin atom is rendered five-coordination in a trigonal bipyramidal configuration by coordinating with S atoms of dithiocarbamate groups. For complex 5, the central Sn atom exists in a skew-trapezoidal planar geometry defined by two asymmetrically coordinated dithiocarbamate ligands and two 3-chlorobenzyl groups.
