" The metal d-orbitals that are directly facing the ligands in "K_(3)[Co(CN)_(6)]" are "

Explain which of the following compounds has effective atomic number of central metal atom in accordance with Sidwick theory? (1) K_(3)[Fe(CN_(6))] (2) K_(4)[Fe(CN)_(6)]

The number of monodentate ligands which are directly bonded to the metal ion is known as:

The hydridizoation states of the central metal ion in the complexes [Co(NO_(2))_(6)]^(3-) and [Fr(CN)_(6)]^(4-) are

Assertion: K_(4)[Fe(CN_(6)] is diamagnetic and [Fe(H_(2)O)_(6)]Cl_(3) is paramagnetic. Reason: Hybridisation of central metal in K_(4)[Fe(CN)_(6)]" is "sp^(3) d^(2) , which in [Fe(H_(2)O)_(6)]Cl_(3)" is "d^(2) sp^(3) .

Write the ligands and central metal atom of the following compound : K_4[Ni(CN)_4]

Co-ordination no. of Fe in K_3[Fe(CN)_6] is:
