Heteronuclear Complexes of Hg(II) and Zn(II) with Sodium Monensinate as a Ligand.

ABSTRACT: The commercial veterinary antibiotic sodium monensinate (MonNa) binds mercury(II) or zinc(II) cations as thiocyanate [Hg(MonNa)₂(SCN)₂] (1) or isothiocyanate [Zn(MonNa)₂(NCS)₂] (2) neutral coordination compounds. The structure and physicochemical properties of 1 and 2 were evaluated by the methods of single crystal and/or powder X-ray diffraction, infrared, nuclear magnetic resonance, X-ray photoelectron spectroscopies, and electrospray-mass spectrometry. The primary cores of the two complexes comprise HgS₂O₂ (1) and ZnN₂O₂ (2) coordination motifs, respectively, due to the ambidentate binding modes of the SCN-ligands. The directly bound oxygen atoms originate fr
