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.

铂（II），钯（II）和镍（II）配合物基于硫代水杨酰肼和相关配体

硫代水杨酸肼（HSC6H4CONHNH2, 1aH2）与其衍生配体HSC6H4CONHR (R = NCHC6H4-p-Cl；1 bh2 NCHC6H4-o-OH;1 ch2, NCHC10H9Fe;1dH2和NHC6H5；通过x射线晶体结构的测定，发现[Pt(1bH)2(dppf)]·CH2Cl2 （dppf = 1′1-二（二苯基膦）二茂铁）配合物主要通过去质子化硫醇形成键。通过核磁共振、红外光谱、ESI质谱和微量元素分析对配合物进行了表征。31P{1H}NMR证实了[PtCl2(dppf)]与1aH2反应形成S，N螯合物的趋势，以及[Pt(1aH)2(PPh3)2]中出现的异构化。通过非共价相互作用（NCI）分析，证明了在[Pt(1bH)2(dppf)]·CH2Cl2晶体结构中存在S··HN和O··HC吸引相互作用，这些相互作用决定了两种1bH配体的空间取向。Hirshfeld表面分析用于可视化和量化[Pt(1bH)2(dppf)]·CH2Cl2晶体结构中的各种分子间相互作用。

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.
