Abstract
In the title complex, [Sn(C2H2ClO2)2(C4H11Si)2], the SnIV ion is coordinated in a distorted tetrahedral environment formed by two O atoms from two monodenate chloroacetato ligands and two C atoms from two trimethyl silyl ligands. Two further weak intramolecular Sn⋯O contacts [2.744 (2) and 2.655 (2) Å] are formed by the chloroacetato ligands.
