title: Bis(ethyl-eneglycolato-κ(2) O,O')tellurium(IV).
abstract: The title compound, C4H8O4Te, crystallized from a solution of Te(4+) in ethyl-ene glycol. The Te(IV) atom is in a distorted seesaw coordination defined by four O atoms from two different ethyl-eneglycate ligands. The C atoms of the ethyl-eneglycate ligands are disorderd over two positions, with population parameters of 50.3 (6) and 49.7 (6)% indicating a statistical distribution. Due to the possibility to transform the primitive monoclinic unit cell into a metrically ortho-rhom-bic C unit cell, the data are twinned and were refined with the twin law -100/0-10/101 with the relative scale factor refining to 1.82 (4)% for the minor component.
