Synthesis, properties, and molecular structure of bis(thiobenzoato-S)tellurium(II), C<inf>14</inf>H<inf>10</inf>O<inf>2</inf>S<inf>2</inf>Te(II)

The synthesis, properties, and structural characterization of the title compound, C14H10O2S2Te, are reported. The crystals are monoclinic, space group C2/c (No. 15) with a=24.369(6), b=4.333(2), c=14.569(3) Å, and β=109.56(2)°, V=1449.57 Å3, M=402, and Dx=1.843 g cm-3 for Z=4. The structure was solved by the heavy-atom method and refined by full-matrix least squares to R=0.029 and Rw=0.027 for 772 diffractometer data. Crystal structure analysis and IR spectroscopic study indicate that the tellurium is covalently bonded to sulfur. There are weak secondary interactions between tellurium and oxygen which complete an S2O2 coordination around tellurium. © 1984 Plenum Publishing Corporation.
