Tellurium complexes with new, large-bite dithio ligands. The crystal structures of cis- and trans- [Te{Ph2P(S)-N-P(S)(OPh)(2)}(2)] and [(4-MeOC6H4TeCl3)(2){mu-(Pr2P)-Pr-i(S)-Fc-P(S)Pr-i(2)}]

Original language description

Reaction of the protonated large-bite bidentate ligand Ph2P(S)-NH-P(S)(OPh)(2) with [Te{NH2)(2)CS}(4)]Cl-2 resulted in the complex [Te(L-L)(2)] (1a), where (L-L)(-) = Ph2P(S)-N-P(S)(OPh)(2). When (L-L)(-) reacted with 4-MeOC6H4TeCl3, an isomeric complex,1b. resulted. Reaction between the less basic ligand 'Pr2P(S)-Fc-P(S)'Pr-2 (Fc = ferrocene) and 4-MeOC6H4TeCl3 yielded the complex [(4-MeOC6H4TeCl3)(2) {mu-'Pr2P(S)-Fc-P(S)'Pr-2}], (2). X-ray crystallographic studies show that 1a and 1b both are squareplanar complexes of Te(II), 1a being asymmetric and 'cis' with two short Te-S bonds trans to two long Te-S bonds (average bond lengths being 2.5415 and 2.9050 Angstrom). Isomer Ib is centrosymmetric, 'trans', with nearly equal Te-S bond lengths averaging2.6805 Angstrom. Complex 2 is an addition compound where the large dithio ligand bridges two 4-MeOC6H4TeCl3 units through weak Te-S bonds. The resulting coordination around each Te(IV) atom is psi -octahedral with the lone pair of electr
