[Cu-2(mu-dppa)(2)(tptz)(2)](ClO4)(2)center dot 3H(2)O was synthesized by self-assembly with dppa, Cu(I) salt, and tptz in solution (dppa = bis(diphenylphosphino)acetylene, tptz = 2,4,6-tris(2'-pyridyl)-1,3,5-triazine) and characterized by x-ray diffraction, elemental analysis, H-1-nuclear magnetic resonance (NMR) spectra, and P-31-NMR spectra. The complex crystallizes in triclinic space group P-1 with a = 11.2202(5) angstrom, b = 12.5231(6) angstrom, c = 16.9294(8) angstrom, alpha = 105.9860(10)degrees, beta = 108.7270(10)degrees, gamma = 91.1730(10)degrees, V = 2150.18(17) angstrom(3), and Z = 4.
