Di-aqua-bis-(cinnamato-κ(2) O,O')cadmium

Area of Science:

• Coordination Chemistry
• Crystal Engineering
• Materials Science

Background:

• Cadmium complexes are investigated for diverse applications.
• Understanding synthesis pathways is crucial for targeted material design.
• Cinnamic acid and hexa-methyl-ene-tetra-mine are common ligands and reagents.

Purpose of the Study:

• To characterize the unintended cadmium complex, [Cd(C9H7O2)2(H2O)2].
• To elucidate the coordination environment around the cadmium(II) ion.
• To analyze the crystal packing and hydrogen bonding interactions.

Main Methods:

• Single-crystal X-ray diffraction was used for structural determination.
• The synthesis involved the reaction of cadmium nitrate with cinnamic acid and hexa-methyl-ene-tetra-mine.
• Structural analysis focused on coordination geometry and intermolecular interactions.

Main Results:

• The complex [Cd(C9H7O2)2(H2O)2] was obtained as an unintended product.
• The cadmium(II) ion exhibits a distorted trigonal-prismatic coordination geometry.
• V-shaped molecules form an interlocking arrangement, stabilized by O-H⋯O hydrogen bonds into a 2D network.

Conclusions:

• The unexpected formation of the cadmium complex provides insights into reaction outcomes.
• The trigonal-prismatic coordination and 2D network highlight unique structural features.
• This study contributes to the understanding of cadmium coordination chemistry and crystal engineering.
