摘要：

A unique cyanide-bridge mixed-valence Cu-I/Cu-II clathrate of formula [Cu-2(I)(CN)(3)][{Cu-II(tren)}(2)(mu-CN)](CF3SO3)(2) [tren = tris(2-aminoethyl)amine] containing cyanide-bridged [{Cu-II(tren)}(2)(mu-CN)](3+) binuclear cations stacked between anionic honeycomb layered copper(I) cyanide networks, was synthesized and structurally characterized by single crystal X-ray diffraction. Variable-temperature magnetic susceptibility studies showed that the cyanide bridge mediates a strong antiferromagnetic interaction between the copper(II) centers (J = -160 cm(-1), the spin Hamiltonian being defined as H = -J S-A.S-B).
