Abstract
Hybrid guanidine ligands and their metal complexes are an important field of research due to their diverse applications and highly modular structure. In this work, the synthesis of four bench-stable iron(III) and zinc(II) complexes of two novel tridentate guanidine-Schiff-base ligands is presented. Although the ligands themselves were found to be unstable, the preparation of the stable metal complexes could be conducted on a gram scale and in high yields (≥88%) without isolation of the corresponding unstable ligand. All complexes were characterized by single-crystal X-ray diffraction, and their structural features are discussed.
Primary Data
Crystallographic data for complexes C1–C4 have been deposited at the Cambridge Crystallographic Data Centre (CCDC) as supplementary no. CCDC – 2452469 for C1, CCDC – 2452470 for C2, CCDC – 2452471 for C3, and CCDC – 2452472 for C4. Additional information on the synthesis and characterization of the presented new compounds is available via the Chemotion Repository. The respective links are given at the end of the experimental procedures.
