1 Source of materials

The hexacoordinated divalent cobalt complex was synthesized via a volatile compound saturated solution method. The detailed preparation procedure was as follows: (1) 0.4 mmol (0.11 g) of 4-allyl-2-methoxyphenyl nicotinate was dissolved in 20 mL of ethanol to obtain solution A; (2) 0.1 mmol (0.024 g) of CoCl2⋅H2O was dissolved in 5 mL of deionized water to prepare solution B; (3) 0.2 mmol (0.019 g) of KSCN was dissolved in 5 mL of deionized water to form solution C; (4) Solutions B and C were thoroughly mixed and subsequently poured into solution A under continuous stirring. The resulting pale-red transparent mixture was allowed to stand at room temperature for natural evaporation. After several days, pale-red transparent block crystals were obtained at the bottom of the container, corresponding to the target cobalt(II) coordination complex.

2 Experimental details

Data acquisition was performed using φ and ω scans, and the collected diffraction intensities were processed with empirical absorption corrections via the SAINT 1 and SADABS 2 programs. After absorption correction, the crystal structure was solved using the Olex2 software 3 and the programs SHELXT 4 program and refined with SHELXL, 5 and the molecular graphics were drawn by using DIAMOND software. 6 All hydrogens were generated geometrically (C–H bond fixed at 0.96 Å), assigned isotropic thermal parameters, and allowed to ride on their parent carbon atoms before the final cycle of refinement.

3 Comment

Recent advances in supramolecular and coordination chemistry have underscored the significance of metal-organic complexes as multifunctional materials. Cobalt, an essential bioelement, plays critical roles in biological systems, where it exclusively exists in coordinated forms (e.g., vitamin B12 coenzymes 7 ) to mediate redox reactions and enzymatic processes. 8 Beyond biology, cobalt complexes exhibit versatile applications in catalysis, magnetism, and medicine due to their tunable redox states (Co2+/Co3+), diverse coordination geometries, and ligand-field effects. 9 , 10 , 11 , 12

Natural products, particularly those in traditional Chinese medicine (TCM), often serve as ligands for metal ions. Flavonoids, anthraquinones, and alkaloids – rich in hydroxyl, carbonyl, and amino groups – readily coordinate with transition metals like cobalt, enhancing their bioavailability and pharmacological activity. For instance, rutin and astragalosides form stable Co2+ complexes in aqueous decoctions, which may underpin their therapeutic effects. Despite this, systematic studies on structurally defined Co complexes derived from TCM ligands remain limited. 13

Herein, we report the synthesis and characterization of a hexacoordinated Co(II) complex using nicotinyl eugenolate, a hybrid ligand combining nicotinic acid and eugenol (a phenolic phytochemical). This ligand’s N,O-donor architecture enables robust coordination with Co2+, while its natural product origin aligns with green chemistry principles.

The hexacoordinated cobalt(II) complex crystallizes that the asymmetric unit contains half a Co(II) ion, two 4-allyl-2-methoxyphenyl nicotinate molecules, and one thiocyanate anion. The central Co(II) ion adopts a six-coordinate geometry, ligated by four nitrogen atoms from the pyridine rings of two 4-allyl-2-methoxyphenyl nicotinate ligands and two nitrogen atoms from thiocyanate anions, forming a discrete zero-dimensional (0D) structure. These 0D units are interconnected via C–H⋯O hydrogen bonds between the aromatic C–H groups of the pyridine rings and the carbonyl oxygen atoms of adjacent ligands, generating a two-dimensional (2D) layered architecture. Notably, these 2D layers further interpenetrate through additional C–H⋯O interactions involving the methoxy and hydroxyl groups of the eugenol moieties, resulting in a three-dimensional (3D) supramolecular framework. The cohesive packing is further stabilized by π-π stacking interactions (3.6–3.8 Å). Bond lengths and angles are all in the expected ranges. 14
