I found the field of Chemistry very interesting. Saw the article Physicochemical and X-ray crystallographic properties of the first rhenium compound of benzophenone thiosemicarbazone (bptsc), fac-[Re(CO)(3)(K-2-N-im,S-bptsc)Cl] published in 2021.0. Formula: C13H10O, Reprint Addresses Bakir, M (corresponding author), Univ West Indies, Dept Chem, Mona Kingston 7, Jamaica.. The CAS is 119-61-9. Through research, I have a further understanding and discovery of Benzophenone
fac-[Re(CO)(3)(kappa(2)-N-im,S-bptsc)Cl] (2), isolated from the reaction between Re(CO) 5 Cl and benzophenone thiosemicarbazone, bptsc, (1) in refluxing toluene in air, is the first Re compound of 1 and is the second Re(CO)(3)Cl compound of kappa(2)-N-im,S-coordinated ligand (im = imine). The authenticity of 2 was established from the results of its elemental composition, spectroscopic measurements, and X-ray crystallographic analysis. Single crystals of 2 grown from DMF are in the monoclinic space group P2(1)/c. The asymmetric unit of 2 revealed pseudo-octahedral coordination about Re. Two carbonyl C atoms, an imine N atom and a thione S atom occupy the equatorial sites and the axial sites are occupied by a carbonyl C atom and a Cl atom. The kappa(2)-N,S-coordination of 1 to Re forms a semi-planar five-membered [Re-N-N-C-S] metallocyclic ring. The extended structure disclosed stacks of molecules interlocked via a web of N-H center dot center dot center dot X (X = Cl or O), S center dot center dot center dot S and C-H center dot center dot center dot pi interactions. DFT calculations divulged facile delocalization of electron density in the molecule and interatomic distances and angles in good agreement with the solid state structure. Electrochemical measurements on 2 in CH3CN and DMF revealed sequential irreversible electron transfers pointing to structural changes due to electrochemically induced thione-thiol tautomerization of the thioamide moiety. Plausible mechanisms for the oxidative and reductive electrochemical decomposition of 1 and 2 are reported. The proposed mechanisms are in good agreement with those reported in the literature for closely related compounds. (c) 2021 Elsevier B.V. All rights reserved.
