Abstract: Reaction of iodoacetic acid with cupric carbonate in water in dimmed light yields green Cu(ICH₂COO)₂.H₂O (1). From X-ray crystallography, it is found to be a tetra-acetato bridged copper(II) dimer with the water molecules occupying the apical positions. In thermogravimetry, the coordinated water molecules are lost in the temperature range 50-100ºC. From magnetic susceptibility meas-urements in the temperature range 300-1.8 K, the exchange cou-pling constant J is found to be -142(1) cm⁻¹ and g = 2.18(2) with the spin Hamiltonian H = -2J{SCu₁•SCu₂}. It reacts with 2,2'-bipyridine (bpy) to yield [Cu(bpy)₂I]I. It oxidises thiophenol to Ph-S-S-Ph under dry N₂ atmosphere.Reaction of iodoacetic acid with cupric carbonate in water in dimmed light yields green Cu(ICH₂COO)₂.H₂O (1).
