ETHYLDITHIOCARBAMATO)DIIODO-(PHENYL)TELLURIUM(IV), PHTE(S(2)CNET(2))I-2, AND ITS METHOXY-SUBSTITUTED MIXED BR I ANALOG HYLDITHIOCARBAMATO)(4-METHOXYPHENYL)TELLURIUM(IV), P-MEOC(6)H(4)TE-(S(2)CNET(2))(BR0.4I0.6)(2)/

The Te-IV complexes PhTe(S(2)CNEt(2))I-2, (1), and p-MeOC(6)H(4)Te(S(2 )CNEt(2))(Br-0.4/I-0.6)(2), (2), have been synthesized by reacting PhT eI(3) with NaS(2)CNEt(2), and p-MeOC(6)H(4)Te(S(2)CNEt(2))(2)I with Br -2, respectively. In (2), both I atoms are partially replaced by Br at oms in a 3:2 ratio. The structures display distorted octahedral Te coo rdination with two symmetrically coordinated S atoms [Te-S 2.550 (2)-2 .569 (2) Angstrom in three independent molecules of (1) and 2.523 (1) and 2.535 (1) Angstrom in (2)] and with two cis-disposed halogen atoms [Te--I 2.941 (1) 2.986 (1) Angstrom, in (1) and 3.003 (4) and 3.049 ( 3) Angstrom in (2); Te-Br 2.962(8) and 2.967 (8) Angstrom in (2)] in e quatorial positions. The aryl group is axial in both complexes [Te-C 2 .137 (6)-2.146 (6) and 2.123 (5) Angstrom in (1) and (2), respectively ] and the second axial position is occupied by a halogen atom of a nei ghbouring molecule [Te ... I 3.898 (1)-4.233 (1) Angstrom in (1); Te . .. I 3.872 (3) Angstrom and Te ... Br 3.676 (6) Angstrom in (2); trans angles C-Te ... I(Br) 153.4(2)-177.7 (2)degrees] so that the molecule s are joined into (quasi)centrosymmetric pairs by these secondary inte ractions.
