accomplished. They afford binuclear copper(II) complexes of the formula [Cu2L2][BPh4]2(L = L1 or L2). The structure of [Cu2L12][BPh4]2 was determined by single-crystal X-ray analysis. It crystallizes in the triclinic space group P with a= 13.437(4), b= 15.192(5), c= 12.364(4)Å, α= 116.38(3), β= 113.71(3), γ= 60.48(2)°, and Z= 1. The complex has a binuclear structure doubly bridged by the pyrazolate groups
