dc.abstract.en Three new cyanido-bridged discrete bimetallic assemblies based on $\left [ W\left ( CN \right )_{6}\left ( bpy \right ) \right ]^{2-}$ building block have been synthesised and structurally characterised. Neutral molecular square $\left \{ \left [ Ni\left ( bpy \right )_{2} \right ]_{2}\left [ W\left ( CN \right )_{6}\left ( bpy \right ) \right ]_{2} \right \}\cdot nH_{2}O \left ( 1 \right )\left ( bpy=2,{2}'-bipyridine \right )$ has been constructed from $\left [ Ni^{II} \left ( pby \right )_{2}\left ( H_{2}O_{2} \right )\right ]^{2+}$ complex. Since the attempt to obtain analogous structure with Cu(II) ion was unsuccessful, we introduced tetradentate blocking ligand tren (tren = tris(2-aminoethyl)amine) on Cu, which resulted in dinuclear molecule $\left \{ \left [ Cu\left ( tren \right ) \right ]\left [ W\left ( CN \right )_{6}\left ( bpy \right ) \right ] \right \}\left ( 2 \right )$. In order to create square cluster with Cu(II) ions we employed tridentate ligand di-(2-picolyl)amine (dpa), which yielded the desired structure of $\left \{ \left [ Cu\left ( dpa \right ) \right ]_{2} \left [ W\left ( CN \right )_{6}\left ( bpy \right ) \right ]_{2}\right \} \left ( 3 \right )$. Compounds (1) and (3), the first molecular squares based on $\left [ W\left ( CN \right )_{6}\left ( bpy \right ) \right ]^{2-}$ building block, are paramagnetic and follow the Curie law. pl
