Abstract The title compound [Cu4(NH3)12-(µ2-CN)8-Pd4(CN)8] was prepared from the aqueous solution Cu2+ – N,N,N′,N′-tetraethylethane-1,2-diamine – [Pd(CN)4]2−, where the addition of excess amounts of ammonia caused the dissolution of the precipitate formed during reaction. Using this method, we prepared and structurally characterized the new complex of Cu(II) containing ammine ligand with tetracyanidopalladate(II) anion incorporated within the molecule. The crystal structure of compound is molecular; the unit cell contains centrosymmetric octanuclear molecules in which all central atoms lies on mirror plane. Generally, the structure of the molecule can be divided into central cyclic part and terminal pendants. The structure contains nitrogen atoms derived from the ammonia molecules coordinated to Copper(II) atoms. They are involved in the formation of N-H···N hydrogen bonds type.
