Abstract A new trinuclear Cu(II) complex with isonicotinic acid N-oxide, [Cu3(N-inicO)4(OH)2(H2O)5·2H2O, has been prepared and its crystal structure determined by X-ray analysis. The complex crystallizes in the monoclinic space group P2/c with a = 12.051(4), b = 7.043(2), c = 19.825(6) A, β = 98.51(2)° and Z = 2. The arrangement of the three Cu atoms is triangular, with distances of 3.365(1) A between the central and terminal Cu atoms. The coppers are pentacoordinated; the coordination geometry is tetrahedral distorted square pyramidal for the terminal Cu atoms and elongated square pyramidal for the central Cu atom. Two hydroxo ligands and two of the four isonicotinato N-oxide ligands through the carboxyl group form bridges between Cu atoms. In addition to five coordinated waters, two lattice waters are present. The least-squares refinement led to a final R of 0.044.
