The bis(di-n-butyltin) derivative of 2,5-bis(2-hydroxyethylamino)-1,4-benzoquinone was synthesized and characterized by common spectroscopic techniques. In solution, discrete molecules with pentacoordinate tin atoms were observed, whereas the X-ray diffraction analysis of the solidstate structure revealed polymeric chains that were due to intermolecular Sn···O bonds. In vitro tests demonstrated that the tin compound displays bactericidal activity against a wide range of aerobic and anaerobic bacteria. Acute toxicity tests indicated that the di-n-butyltin compound has a rela-
