Structure of a diorganotelluroxonium(IV) cation, {[2,6-(CH2NMe2)2C6H3Te(μ-O)]2}2+, with the trichlorido(dimethyl sulfoxide)platinum(II) anion

Abstract

In the title salt, di-μ-oxido-bis{2,6-bis[(dimethylamino)methyl]phenyl-κC1}tellurium(IV) bis[trichlorido(dimethyl sulfoxide-κS)platinate(II)], (C24H38N4O2Te2)[PdCl3(C2H6OS)]2, which crystallizes in the triclinic space group P\overline{1}, each Te atom is in a distorted five-coordinated TeO2N2C square-pyramidal geometry (τ values of 0.026 and 0.001) with the C atoms of the phenyl rings occupying the apical positions. The phenyl rings in the [C24H38N4O2Te2]2+ cation are in a cis arrangement to enable this species to participate in Te...Cl cation–anion interactions. There are also C—H...O interactions involving the dimethyl sulfoxide ligands and numerous cation–anion and anion–anion C—H...Cl interactions, which link the ions into a complex three-dimensional array.
