A novel two-dimensional cyanide-bridged polymer [Cu-II(tren)]{Cu-I[W-V(CN)(8)]}.1.5H(2)O (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 {Cu-I[W-V(CN)(8)]} square grid built of Cu-I centres of tetrahedral geometry coordinatively saturated by CN bridges and [W-V(CN)(8)](3-) capped by [Cu-II(tren)](2+) moieties; it exhibits ferromagnetic coupling J(1) = +5.8(1) cm(-1) within the Cu-II-W-V dinuclear subunits and weak antiferromagnetic coupling J(2) = -0.03(1) cm(-1) between them through diamagnetic Cu-I spacers.
