Crystal structure, Hirshfeld surface analysis and photocatalytic activities of a cobalt(III) complex based on acid and alkaline mixed ligands

A novel Co(III) complex [Co(chda)(nta)] ( 1 ) (chda = trans-(1R,2R)-1,2-cyclohexanediamine, H 3 nta = nitrilotriacetic acid) was synthesized based on chda and H 3 nta ligands at room temperature. Complex 1 was structurally identified by single-crystal X-ray diffraction, elemental analysis, FT-IR and...

Description
Summary:A novel Co(III) complex [Co(chda)(nta)] ( 1 ) (chda = trans-(1R,2R)-1,2-cyclohexanediamine, H 3 nta = nitrilotriacetic acid) was synthesized based on chda and H 3 nta ligands at room temperature. Complex 1 was structurally identified by single-crystal X-ray diffraction, elemental analysis, FT-IR and Raman spectrum. Complex 1 was connected by the intermolecular N–H···O hydrogen bonds to form a 2D supramolecular structure. The 3D Hirshfeld surface and 2D fingerprint plots were used to further study the intermolecular interactions of complex 1 . The intermolecular O···H and H···H contacts were the most significant interactions in the crystal, which comprised 96.6% of the total Hirshfeld surface. In addition, complex 1 exhibited excellent photocatalytic activity for the removal of methylene blue under UV light. The possible photocatalytic mechanism and reaction kinetics were also discussed.
