What is the coordination number of the Fe atom in K3[Fe(C2O4)3]?
is it 6?
Six is correct.
Yes, the coordination number of the Fe atom in K3[Fe(C2O4)3] is indeed 6. The coordination number refers to the number of ligands that are directly coordinated to the central metal atom/ion.
To determine the coordination number of the Fe atom in K3[Fe(C2O4)3], you need to examine the chemical formula and the coordination complex. In this case, the formula shows that there are three C2O4 (oxalate) ligands coordinated to the Fe atom.
Each oxalate ligand consists of two oxygens (O) and two carbon atoms (C). Each oxygen atom can act as a donor atom to coordinate to the central Fe(III) ion. Therefore, there are a total of six donor atoms from the C2O4 ligands that are coordinated to the Fe ion.
Hence, the coordination number of the Fe atom in K3[Fe(C2O4)3] is 6.
