| Summary: | The asymmetric unit of the title complex, [Cu4Fe(CN)6(C6H18N4)4][Fe(CN)5(NO)]2·6H2O, comprises a complex [{Cu(tren)CN}4Fe(CN)2]4+ [tren is tris(2-aminoethyl)amine] cation, which exhibits -1 symmetry with the terminal cyanide ligands oriented trans to each other, and two [Fe(CN)5(NO)]2− nitroprussiate counter-anions. In the crystal, N—H...N hydrogen-bonding interactions are observed between H atoms on the primary amine groups of the tren ligand and the terminal cyanide groups of the nitroprussiate counter-ions. The N atom in the terminal CN ligand of the cation is equally disordered over two positions. The structure also contains disordered lattice water molecules. Their contribution was eliminated from the refinement using the procedure described by van der Sluis & Spek (1990). |
