Answer 2

Formula for the compound sodium hexacynoferrate (III) is $Na_{3} [Fe (CN)_{6} ]$

Explanation:

• Complex compound is a type of compound formed by bonding between a central metal atom as well as surrounding non-metal atoms or ions or ligands bound by covalent, ionic or coordination bonds.
• Warner's principle is used to describe complex compound with their structure.
• Examples of complex compounds include potassium ferrocyanide K4 [Fe(CN) 6] and potassium ferrocyanide K3 [Fe(CN) 6]. Other examples include pentamine chloro cobalt(III) chloride [Co(NH)5Cl]Cl2 and dichlorobis(ethylenediamine) platinum(IV) nitrate [Pt(en)2Cl2](NO3)2.
• Coordination compounds, any class of substances with chemical structures in which a central metal atom is surrounded by nonmetal atoms or groups of atoms, called ligands, are joined by chemical bonds.
