13C nmr chemical shifts are reported for some aromatic and aliphatic tellurium compounds.For a given organic group, the shift of the C1 atom varies in the order RTeCl4- >/= RTeCl3 > R2TeCl2 > R2Te > R2Te2, as expected from electronegative considerations.The C2 atom experiences an opposite trend while the C3 and C4 atoms of the ring experience smaller changes.The chemical shifts of para-substituted aromatic tellurium compounds do not show additivity of contributions from the substituents.
