新型二维氰化物桥接聚合物[CuII(tren)]{CuI[W(V)(CN)8]}。由[Cu(tren)(OH2)]2+与[W(V)(CN)8]3-同时原位金属-配体氧化还原反应生成的1.5H2O （tren = tris（2-氨基乙基）胺）和与[W(V)(CN)8]3-的自组装构成一个由CN桥协调饱和的四面体几何CuI中心和由[CuII(tren)]2+覆盖的[W(V)(CN)8]3-组成的{CuI[W(V)(CN)8]}正方形网格；它在CuII-W(V)双核亚基内表现出铁磁耦合J1 = +5.8(1) cm(-1)，在它们之间通过抗磁性CuI间隔段表现出弱反铁磁耦合J2 = -0.03(1) cm（-1）。
A novel two-dimensional cyanide-bridged polymer [CuII(tren)]{CuI[W(V)(CN)8]} . 1.5H2O (tren = tris(2-aminoethyl)amine) formed via the simultaneous in situ metal-ligand redox reaction of [Cu(tren)(OH2)]2+ and self-assembly with [W(V)(CN)8]3- consists of a {CuI[W(V)(CN)8]} square grid built of CuI centres of tetrahedral geometry coordinatively saturated by CN bridges and [W(V)(CN)8]3- capped by [CuII(tren)]2+ moieties; it exhibits ferromagnetic coupling J1 = +5.8(1) cm(-1) within the CuII-W(V) dinuclear subunits and weak antiferromagnetic coupling J2 = -0.03(1) cm(-1) between them through diamagnetic CuI spacers.
