X-ray powder diffraction, thermogravimetric analysis, IR, and variable-temperature magnetic susceptibility. It crystallizes
in cubic, space group Fd3̄c with a = 24.644(3) Å, V = 14967(3) Å3, and Z = 96. Its framework is the first 3D
structure using coordinative interactions constructed via trinuclear triangular CuII secondary building units, in which
both CuII ions and trz ligands act as three-connected nodes to form a 6.82 net. An overall antiferromagnetic behavior
was found in the compound.
