Abstract
Ten
compounds of diphenyltin(IV) with N-dialkyldithiocarbamate were successfully prepared using in situ methods. Elemental analysis data
(C, H, N and S) showed an agreement with the general formula of (C6H5)2Sn[S2CNR1R2] (R1
= CH3, C2H5, C7H7; R2 = C2H5,
C4H9, C6H11, iC3H7, C7H7). The
structures of these compounds have been examined by infrared spectroscopy,
ultraviolet, 1H, 13C & 119Sn NMR
spectroscopy and X-ray crystallography. The infrared spectra of these compounds
showed three important peaks for v(CN), v(CS) and v(CS) bands that appeared in the region of 1474 -1499, 969 - 995
and 324 - 335 cm-1 respectively. Data for 13C NMR
spectroscopy showed an important peak in the region of 198 – 200 ppm that
corresponded to the NCS2 group. Single crystal X-ray diffraction
studies showed (C6H5)2Sn[S2CN(C2H5)(CH3)]2
(1) is six coordinated and
adopted a monoclinic system with
space group C2/c, while (C6H5)2SnCl[S2CN(C7H7)(iC3H7)] (2) is five coordinated, crystallized in
monoclinic system with space group Pb1/n. Meanwhile, six
coordinated (C6H5)2Sn[S2CN(CH3)(iC3H7)]2 (3) adopted a orthorhombic system with a space group Pbcn.
Keywords: diphenyltin(IV), dithiocarbamate.
