YL)TELLURIUM(IV),P-MEOC(6)H(4)TE-(S(2)CNET(2))(3), AND THE TRICLINIC MODIFICATION OF ARBAMATO)PHENYL-TELLURIUM(IV),PHTE(S(2)CNET(2))(3)

The structures of the tellurium(IV) complexes [Te(C5H10NS2)(3)(C7H7O)] , (1), and [Te(C5H10NS2)(3)(C6H5)]1, (2) (the triclinic modification), have been investigated. In both structures the coordination of the Te atom is distorted pentagonal bipyramidal, with four S atoms from two near symmetrically bidentate dithiocarbamate ligands [Te-S 2.625(1)-2. 889(1)Angstrom] and a fifth S atom from the third unsymmetrically bide ntate dithiocarbamate ligand [Te-S 2.585(1)-2.602(1)Angstrom] in equat orial positions. The aryl group is axial [Te-C 2.148 (5)-2.160 (3) Ang strom]; the second axial position is occupied by the second S atom of the unsymmetrically bidentate dithiocarbamate ligand [Te ... S 3.235(2 )-3.241(1) Angstrom], the trans angle C-Te ... S being 144.6-147.2(1)d egrees. In the structure of (2), the two crystallographically independ ent molecules have different orientations of the ethyl groups in all t hree ligands and slightly differing phenyl group orientations.
