The synthesis and crystal structure of novel trinuclear molybdenum cluster compoundwith somewha "loose" coordination site {Mo3（μ3-S）(μ-S)3[S2P（OEt）2]4· P（C6H5）3}'·（0.86 CH2Cl2）have been reported. The cluster crystallizes in the spece group Pl with two molecules in a unit cellwhose parameters are a=10.472（4）, b=14.375（2）, c=21.695（3）; a=74.O4（1）°, β=76.50（2）°, γ=72.22（2）°, v=2950 and D_o=1.693 ***-x. On the basis of 4840 independent reflections with I≥2σ（1）.the structure was solved by heavy atom method and Fourier method and refined by full-matrixleast-squares techniques to a final R=0.058. The distances between Mo atoms in this cluster are 2.731（1）, 2.748（1） and 2.753（1） *** mean value of Mo--Mo bond lengths is slighly shorter than those in other trinuclear Mo clusterswith "looscly coordinated" site. In addition, the PPh3ligand is loosely coordinated to one Mo atomin direction opposite to the μ3-S with Mo--P bond length of 2.647（3）. This is different from theother strocturally analogous clusters, in which the loosely coordinated ligand is trans to μ2--S. Asummary of Mo--Mo and Mo-L bonding for such clusters is given.

Two-dimensional (2D) materials, such as MoS2, have been considered as a competitive coordinate for future electronics due to their excellent electrostatics and high mobility [1–3]. Moreover, the potential integration of 2D materials with silicon circuits can present increased density and multifunction in future heterogeneously integrated circuits [4,5]. However, the high thermal-budget during Mo S2 synthesis exceeds the temperature requirement of direct integration with Si in the back-end-of-line (BEOL) fabrication process [6–8].

The present study aimed to explore the potential of artificial intelligence(AI)methodology based on magnetic resonance(MR)images to aid in the management of prostate cancer(PCa).To this end,we reviewed and summarized the studies comparing the diagnostic and predictive performance for PCa between AI and common clinical assessment methods based on MR images and/or clinical characteristics,thereby investigating whether AI methods are generally superior to common clinical assessment methods for the diagnosis and prediction fields of ***,we found that,in the included studies of the present study,AI methods were generally equal to or better than the clinical assessment methods for the risk assessment of PCa,such as risk stratification of prostate lesions and the prediction of therapeutic outcomes or PCa *** particular,for the diagnosis of clinically significant PCa,the AI methods achieved a higher summary receiver operator characteristic curve(SROC-AUC)than that of the clinical assessment methods(0.87 vs.0.82).For the prediction of adverse pathology,the AI methods also achieved a higher SROC-AUC than that of the clinical assessment methods(0.86 vs.0.75).Second,as revealed by the radiomics quality score(RQS),the studies included in the present study presented a relatively high total average RQS of 15.2(11.0–20.0).Further,the scores of the individual RQS elements implied that the AI models in these studies were constructed with relatively perfect and standard radiomics processes,but the exact generalizability and clinical practicality of the AI models should be further validated using higher levels of evidence,such as prospective studies and open-testing datasets.

The additive reaction of SbCl3to trimolybdenum clusters with loose coordination sites,Mo3（μ3-S）(μ-S)3[S2P （OEt）2]4·L′（1L′=H2O; 2, L′=C3H3ON）, in a C2H5OH-HCl medium yieldscomplexes {Mo3（μs-S） [（μ-S）3·SbCl3] [S2P （OEt）2]4·（C2H6OH）}（C2H5OH）（3） and {Mo3（μ3-S） [（μ-S）3·SbCl3] [S2P （OEt）2]3[SXP （OEt）2] · （C3H3ON）} （X=S,O）（4）, respectively. The crystal and mo-lecular structures of these two compounds have been determined by single crystal X-ray crystallography:crystal 3 belongs to the monoclinic system, P21,/n, while crystal 4 belongs to the trielinic system, P1,The intensity data were collected on an Enraf-Nonius CAD-4 diffractometer with graphite-monochro-matized MoKα radiation by using the ω-2θ technique. The structures were solved by the Pattersonmethod as well as direct methods and refined by full matrix least-squares method. Final R values were0.078 for crystal 3 and 0.068 for crystal 4, respectively. The result of the structure determination showedthat the two molecular structures are practically formed by connecting a trimolybdenum clusterswith loose coordination sites,{Mo3（μs-S）（μ-S）3[S2P（OEt）2]4·L （L=C2H5OH, C3H3ON）, with a SbCI3molecule through three （μ-S）atoms to form the {Mo3SbS4} core of a cubane-like type. There arerelatively weak coordination bonds between the Sb and the three （μ-S） atoms, while no bonding in-teraction between the Sb and the three Mo atoms is found. In the additive compounds the structuralcharacter of the trimolybdenum clusters with loose coordination sites has significantly been *** addition, 3 still has the reactivity for the loosely coordinated EtOH to be replaced by an oxazole ringto form crystal 4. However, the three （μ-S） atoms may be regarded as triple bridging S atoms eachconnecting two Mo atoms and a Sb atom. The information obtained serves as an evidence that thetetranuclear clusters might be formed by a [3+1] reaction mode.
