The reaction of the title ligand (H 2DAPTSC) with SnR 2O (R=Me, Ph) in DMF afforded the complexes [SnR 2(DAPTSC)]. The phenyl derivative crystallizes as [SnPh 2(DAPTSC)]·2DMF in the P2 1/ n space group, with lattice constants: a=9.753(1), b=18.962(1), c=17.923(3) Å, β=97.93(1), Z=4 and R=0.035. The molecular complex is pentagonal bipyramidal, with the five donor atoms of the ligand in the pentagonal plane and the two phenyl groups in the axial positions. A comparative study based on the spectral properties (IR, Mössbauer and 1H, 13C and 119Sn NMR spectroscopy) of the two complexes suggests a similar structure for [SnMe 2(DAPTSC)].
