Tris(ethyl carbazate-κN,O)nickel(II) dinitrate.

Area of Science:

• Inorganic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Nickel complexes are vital in catalysis and materials science.
• Understanding the structural nuances of coordination compounds is key to predicting their properties.

Purpose of the Study:

• To elucidate the crystal structure of the novel nickel(II) complex, [Ni(C(3)H(8)N(2)O(2))(3)](NO(3))(2).
• To investigate the coordination geometry and intermolecular interactions within the crystal lattice.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of hydrogen bonding interactions (N-H···O) was performed.

Main Results:

• The asymmetric unit contains two independent nickel(II) cations, each exhibiting a facial (fac) coordination geometry (fac-NiN(3)O(3) octahedron).
• Four nitrate anions are present in the unit cell.
• Extensive cation-to-anion N-H···O hydrogen bonds, including bifurcated interactions, were identified, playing a significant role in stabilizing the crystal structure.

Conclusions:

• The detailed crystal structure of [Ni(C(3)H(8)N(2)O(2))(3)](NO(3))(2) was successfully determined.
• The study highlights the importance of hydrogen bonding in the supramolecular assembly and stability of this nickel coordination complex.
