Abstract: The title compound, [Cr(C₄H₁₀O₂)(C₁₂H₂₇O₃SSi)₂], is a molecular chromium(II) thiolate that has the 1,2-dimethoxyethane ligand coordinating through one of its two O atoms. The metal is O,S-chelated by the thiolate anion, and the O atom from the 1,2-dimethoxyethane ligand occupies the apical position of the square-pyramidal coodination geometry. The asymmetric unit contains two molecules. Three C atoms of one ^tBu group are disordered approximately equally over two positions. One C atom of another ^tBu group is disordered over two positions, with site occupancies of ca. 0.6 and 0.4.
