Diaqua-bis-(l-lactato)magnesium.

Area of Science:

• Coordination Chemistry
• Crystal Engineering
• Supramolecular Chemistry

Background:

• Magnesium complexes play vital roles in biological systems and materials science.
• Understanding the coordination environment and self-assembly of metal-organic compounds is crucial for designing new functional materials.

Purpose of the Study:

• To characterize the crystal structure and supramolecular assembly of a novel magnesium-lactate complex.
• To investigate the coordination geometry around the magnesium ion and the role of hydrogen bonding in structure formation.

Main Methods:

• Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
• Analysis of intermolecular interactions, including hydrogen bonding, was performed to understand the supramolecular architecture.

Main Results:

• The magnesium cation (Mg2+) exhibits a six-coordinated, distorted octahedral geometry (MgO6).
• Coordination involves four oxygen atoms from two lactate anions and two water molecules.
• Complex molecules self-assemble into helical chains along the 'a' crystallographic axis via O-H⋯O hydrogen bonds.
• These chains are further interconnected by hydrogen bonding, creating a robust three-dimensional supramolecular network.

Conclusions:

• The study successfully elucidated the detailed crystal structure of the magnesium lactate complex.
• Hydrogen bonding is the primary driving force for the formation of the intricate 3D supramolecular architecture.
• The findings contribute to the understanding of metal-organic coordination compounds and their self-assembly principles.
