The title compound {Mo3 (μ3,-S) (μ-S)3 [μ-SOp (OEt )2] [S2p (OEt)2]3(CH3CN) }. CH3CN, C20H46,Mo3N2O9p4S11, Mr= 1222. 9, has been synthesized bythe reaction of [Mo3 (μ3,-S) (μ-S)3]4+ with Hdtp (hydrogen diethyldithiophosphate)and its structures was dctermined by X-ray crystallography. The crystal data for the title compound: triclinic, p1, Z= 2, a= 13. 011 (8), b= 13. 411 (9), c= 14. 385 (5)A, a=76. 59(5), B=78. 09(5), Y=82. 20(3), V= 2382(2) A3, Dc= 1.705 g/cm3, μ (MoKa) = 1. 434 mm-1, F (000) = 1228. The structure was refined to r =0.080 for 5485 observed reflections. Quasi-aromaticity in the puckered-ring of Mo3S3was experimentally probed by 31p NMr spectroscopic measurements. The 31p chemicalshifts of ligand DTp’s (diethyldithiophosphate) were modulated by the substituent effect of the adjacent bridging aromatic carboxylate through the long-distance super-conjugation via the trinuclear Mo cluster core.

Owing to their exceptional properties, high-entropy alloys(HEAs) and high-entropy materials have emerged as promising research areas and shown diverse applications. Here,the recent advances in the field are comprehensively reviewed,organized into five sections. The first section introduces the background of HEAs, covering their definition, significance,application prospects, basic properties, design principles, and microstructure. The subsequent section focuses on cutting-edge high-entropy structural materials, highlighting developments such as nanostructured alloys, grain boundary engineering,eutectic systems, cryogenic alloys, thin films, micro-nano-lattice structures, additive manufacturing, high entropy metallic glasses, nano-precipitate strengthened alloys, composition modulation, alloy fibers, and refractory systems. In the following section, the emphasis shifts to functional materials, exploring HEAs as catalysts, magneto-caloric materials, corrosion-resistant alloys, radiation-resistant alloys, hydrogen storage systems, and materials for biomedicine. Additionally, the review encompasses functional high-entropy materials outside the realm of alloys, including thermoelectric, quantum dots, nanooxide catalysts, energy storage materials, negative thermal expansion ceramics,and high-entropy wave absorption materials. The paper concludes with an outlook, discussing future directions and potential growth areas in the field. Through this comprehensive review,researchers, engineers, and scientists may gain valuable insights into the recent progress and opportunities for further exploration in the exciting domains of high-entropy alloys and functional materials.

Three dinuclear cyanide-bridged complexes[Fe^(Ⅱ)(pY_(5)OMe_(2))CNM^(Ⅱ)(pY_(5)OMe_(2))](OTf)_(3) (M=Fe1,M=Co 2,M=Mn 3)(pY_(5)OMe_(2)=2,6-bis-((2-pyridyl)methoxymethane)pyridine OTf=CF_(3)SO_(3)^(-)) have been synthesized and ***-crystal diffraction analyses show these three dinuclear compounds are very similar in *** measured ν(CN) results for compounds 1~3 suggest that Mn^(2+) is electron-poorer than Fe^(2+) and Co^(2+).Meanwhile,the temperature dependence of magnetic susceptibilities of complexes 1~3 reveals that in these three complexes,all the cyanide-carbon coordinated Fe(Ⅱ) is low-spin,and Co(Ⅱ) for 2 and Mn(Ⅱ) for 3are both in a high-spin state through 2~400 K but the cyanide-nitrogen coordinated Fe(Ⅱ) for complex 1 exhibits spin crossover (SCO) behavior over 300 K and a hysteresis of 36 K in both cooling and heating modes.

Tanlu fault （Liaozhong segment） goes straight through Liaodong Bay along NNE direc- tion and it is divided into three segments, i.e., the northern segment, the middle segment and the south- ern segment, according to the differences in structural features. There are obvious changes in deposit thickness, sag structure, tectonic nature and other aspects of the layers. Tanlu fault is a special control- ling factor concerning the reservoir formation in Liaozhong sag. First, its activities affect paleogeo- morphology and paleogeographic framework and control the distribution of the sedimentary facies and then they proceed to control the distribution of the source rock and reservoir sand bodies. Second, its activities affect the formation and deformation of the structure, control the formation of abundant traps and cause the destruction of some traps. Third, its activities also affect the juxtaposition relation among the fault, the sand bodies and unconformity surfaces and control the function and efficacy of the three as the main hydrocarbon translocation system. In this paper the hydrocarbon reservoir formation process of JZ21-1, JXI-1 and LD27~2 oil and gas fields, the representatives of Tanlu strike slip fault zone are mainly analyzed. The modes of hydrocarbon reservoir formation can be generalized as follows--hydrocarbon source acts as ＂soil＂ and oil and gas as ＂nutrient＂; hydrocarbon expulsion relies on ＂roots＂; hydrocarbon migration relies on ＂trunks＂; reservoir forms in ＂brunches＂ and the whole process follows the pattern that ＂hydrocarbon accumulates in strike slips and oil and gas reservoir forms like the growth of trees＂.

Two main unknown components in the by-product of camphor hydration synthesis were separated and identified by fine fractional distillation and spectroscopic analyses. The components with different ratios of unknown components A and B were collected by the further distillation. The combined spectral results of GC, MS, GC-MS and 13 C NMr of the collected samples revealed that A is exo-2, 2, 3-trimethylbicyclo[2, 2, 1]heptane, and B is endo-2, 2, 3-trimethylbicyclo[2, 2, 1]heptane.
