Abstract

The reactions of thiosalicylhydrazide (HSC₆H₄CONHNH₂, 1aH₂) and its derivatised ligands HSC₆H₄CONHR (where R = NCHC₆H₄-p-Cl; 1bH₂, NCHC₆H₄-o-OH; 1cH₂, NCHC₁₀H₉Fe; 1dH₂ and NHC₆H₅; 1eH₂) with a variety of platinum(II), palladium(II), and nickel(II) centres were investigated with bond formation predominantly occurring through the deprotonated thiols as revealed by the X-ray crystal structure determination of the [Pt(1bH)₂(dppf)]·CH₂Cl₂ (dppf = 1′1-bis(diphenylphosphino)ferrocene) complex. The complexes were characterised by NMR and FTIR spectroscopy, ESI mass spectrometry, and microelemental analyses. The tendency to form a S,N chelate in the reaction of [PtCl₂(dppf)] with 1aH₂, and an emerging isomerisation in [Pt(1aH)₂(PPh₃)₂] was confirmed by ³¹P{¹H}NMR spectroscopy. Non-covalent interactions (NCI) analysis was carried out to demonstrate the occurrence of S···HN and O···HC attractive interactions in the [Pt(1bH)₂(dppf)]·CH₂Cl₂ crystal structure which determine the spatial orientation of the two 1bH ligands. Hirshfeld surface analysis was used to visualise and quantify the various intermolecular interactions in the [Pt(1bH)₂(dppf)]·CH₂Cl₂ crystal structure.

期刊介绍： Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry. Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
