[NiCl₄]²⁻ is paramagnetic due to the presence of two unpaired electrons in its electronic configuration. Nickel (Ni) in the +2 oxidation state has the electronic configuration 3d⁸. In the tetrahedral complex [NiCl₄]²⁻, one s orbital and three p orbitals of nickel undergo sp³ hybridization, forming four equivalent hybrid orbitals. Each chloride ion donates an electron pair for bonding. Despite the paired electrons from chloride ligands, two unpaired electrons remain in the hybrid orbitals, resulting in paramagnetism in the complex, as unpaired electrons contribute to magnetic moments.

The hybridization in the square planar complex [Ni(CN)₄]²⁻ differs from tetrahedral complexes. In [Ni(CN)₄]²⁻, nickel is in the +2 oxidation state with the electronic configuration 3d⁸. The hybridization scheme involves dsp² hybridization, where one d orbital, one s orbital, and two p orbitals of nickel form four equivalent hybrid orbitals. Each cyanide ion donates a pair of electrons for bonding. This hybridization results in a square planar geometry. In contrast, tetrahedral complexes typically involve sp³ hybridization. The difference lies in the type and number of orbitals involved in the hybridization process, leading to distinct geometries.

The magnetic moment of coordination compounds is measured through magnetic susceptibility experiments. This involves applying an external magnetic field and observing the extent of magnetization. The results provide information about the number of unpaired electrons in the complex. Diamagnetic compounds with all electron spins paired exhibit no magnetic moment, while paramagnetic compounds with unpaired electrons show a magnetic moment.

Metal ions with up to three electrons in the d orbitals exhibit complications in their magnetic behavior. For ions like Ti³⁺ (d¹), V³⁺ (d²), and Cr³⁺ (d³), the magnetic behavior of both free ions and their coordination entities is similar. However, when more than three 3d electrons are present (e.g., d⁴, d⁵, d⁶ cases), the necessary pair of 3d orbitals for octahedral hybridization is not directly available due to Hund’s rule. This leads to complexities, such as the need for pairing of 3d electrons in d⁴ and d⁵ cases, influencing the magnetic properties of the coordination compounds.
When more than three 3d electrons are present, as in d⁴, d⁵, and d⁶ cases, the availability of d orbitals for octahedral hybridization is influenced by the need to pair electrons.

When more than three 3d electrons are present, as in d⁴, d⁵, and d⁶ cases, the availability of d orbitals for octahedral hybridization is influenced by the need to pair electrons. In the d⁴ case (e.g., Cr²⁺, Mn³⁺), a vacant pair of d orbitals is created by pairing one of the 3d electrons. For d⁵ (Mn²⁺, Fe³⁺) and d⁶ (Fe²⁺, Co³⁺) cases, two and three electrons, respectively, need to be paired, creating a vacant pair of d orbitals. This pairing affects the overall magnetic behavior and energy levels in coordination compounds, contributing to their distinct properties.
