In this paper, mixed iodotris (dithiocarbamato )tellurium (IV) complexes with the use of the oxidative replacement reaction via the interaction of TeL4 with iodine have been synthesized.Abstract:
Mixed iodotris ( dithiocarbamato )tellurium(IV) complexes TeL3I (where L- = R1R2NCS2-) have been synthesized with the use of the oxidative replacement reaction via the interaction of TeL4 with iodine. Thus, complexes with R1 = R2 = methyl, ethyl, isopropyl, propyl, and with R1R2N= piperidinyl * have been prepared. A single-crystal structure analysis of one of these, iodotris ( piperidine dithiocarbamato )tellurium, is also reported. In the structure the tellurium atom exists in a distorted pentagonal-bipyramidal environment with the iodine atom and one sulfur atom occupying axial positions. The axial Te-S bond of 2.555(2) A is shorter than the remaining Te-S bonds in the complex [range 2.671(2)-2.722(2) A ]. Crystals are monoclinic, space group P2I/n with unit cell parameters a 9.891(2), b 18.889(2), c 14.762(2) A, β 98.85(2) and Z 4. The structure was refined to final R 0.035 and RW 0.052 for 3283 reflections with 1≥ 1.25 σI).read more
