Abstract [CuII2(L)2Cl4] (1) [L = 2-(benzylthio)ethanamine] has been synthesized and characterized using spectroscopic and X-ray crystallographic results. Structural analyses reveal bidentate chelation behaviour of the neutral L having a distorted square pyramidal coordination environment around each copper(II) with one L, one chloride and two bridging chloro. 1 behaves as an effective catalyst towards oxidation of 3,5-di-tert-butylcatechol to its corresponding quinone with molecular oxygen and also the coupling of o-aminophenol to its phenoxazinone chromophore in methanolic solutions with turnover numbers 2.18 × 102 h−1 (catecholase activity, MeOH), and 3.60 × 102 h−1 (phenoxazinone synthase activity, MeOH) and 2.36 × 102 h−1 (Phenoxazinone synthase activity, MeCN).
