Abstract

Dibenzoyl peroxide in pyridine (py) undergoes facile oxidative addition with metallic copper and affords the complex [{Cu(C6H5CO2)2(py)}2]. Crystals are monoclinic, space group P21/n, with cell parameters a = 10.036(1), b = 10.467(1), c = 17.344(2) Å, β = 98.66(1)°, and Z = 2. The copper atoms are bridged in pairs by four benzoate groups to form binuclear molecules. The copper atom is 0.217 Å out of the plane of the four oxygen atoms (Cu-O from 1.960 to 1.979 Å) to which it is bonded, towards the nitrogen atom of the pyridine ligand. The octahedral co-ordination around the copper atom is completed by the nitrogen atom of the pyridine molecule (Cu-N 2.170 Å) and by the second copper atom (Cu ⋯ Cu 2.658 Å). The binuclear molecule as a whole possesses a centre of symmetry.
