Abstract
Tc(μ-OCCH)Cl is a key starting material for further explorations of dinuclear technetium(III) chemistry and is obtained in 70% yield from readily available starting materials via hydrothermal techniques. Its single crystal X-ray structure reveals the familiar paddle-wheel motif of four bridging acetate groups spanning a short Tc-Tc bond (2.1758(3) Å), augmented by axial chlorides at a Tc-Cl separation of 2.5078(4) Å. The Tc-Tc quadruple bond length is slightly shorter than the one found in the pivalate derivative, Tc(OCCMe)Cl (2.192(1) Å), and slightly longer than found in [Tc(O CCH)](TcO) (2.149(1) Å), the only other structurally characterized members of the small family of Tc(OCR)X dimers. © 2012 Elsevier Ltd.
