Diaqua-(triethano-lamine)copper(II) sulfate monohydrate.

Area of Science:

• Inorganic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Triethanolamine is a versatile ligand in coordination chemistry.
• Copper(II) complexes exhibit diverse structural and electronic properties.
• Understanding hydrogen bonding networks is crucial for materials science.

Purpose of the Study:

• To elucidate the crystal structure of a novel copper(II)-triethanolamine complex.
• To characterize the coordination environment around the copper(II) ion.
• To investigate the intermolecular interactions within the crystal lattice.

Main Methods:

• The asymmetric unit was analyzed, identifying the complex cation, sulfate anion, and uncoordinated water molecule.
• Intermolecular hydrogen bonding was characterized using crystallographic data.

Main Results:

• The copper(II) ion displays a Jahn-Teller-distorted octahedral geometry, coordinated by triethanolamine and water ligands.
• The complex cation, sulfate anion, and lattice water molecule are linked by intermolecular O-H⋯O hydrogen bonds.
• A two-dimensional network structure was formed through these hydrogen bonding interactions.

Conclusions:

• The study provides detailed structural insights into a copper(II)-triethanolamine complex.
• The formation of a 2D hydrogen-bonded network highlights the supramolecular assembly.
• This research contributes to the understanding of metal-ligand interactions and crystal engineering.
