The crystal and molecular structure of sodium pentacyanoammineferrate(II) heptahydrate. Role of intermolecular hydrogen-bond interactions
The crystal and molecular structures of sodium pentacyanoammineferrate(II) heptahydrate have been determined by X-ray diffraction. The Fe-N distance is longer than in the analogous iron(III) complex by 0.06 Å; the Fe-C and C-N distances are similar to those for the hexacyanoferrate(II) species, alth...
