The following papers are very important in the opinion of two referees. They will be published as soon as possible.
New Entangled Coordination Networks Based on Charge-Tunable Keggin-Type Polyoxometalates
Xiu-Li Hao, Yuan-Yuan Ma, Yong-Hui Wang,* Long-Yang Xu, Fu-Chen Liu,* Mao-Mao Zhang, and Yang-Guang Li*
The combination of transition metal ions, bis(triazole) bridging ligands, and various charge-tunable Keggin-type polyoxometalates (POMs) led to the isolation of new entangled coordination networks. The structures of the obtained compounds vary from “zipper-closing” packing to 3D polythreading, 3D polycatenation, and 3D self-penetration, respectively. An increase in the POM negative charges not only increased the number of nodes in the coordination networks but also led to increasingly complicated basic metal–organic building motifs.
Stable Encapsulation of Acrylate Esters in Networked Molecular Capsules
Guo-Hong Ning, Yasuhide Inokuma, and Makoto Fujita*
Networked molecular capsules were obtained that encapsulate acrylate esters in a single-crystal-to-single-crystal fashion to give stable inclusion complexes. Encapsulation of methyl and tert-butyl acrylates was confirmed by single-crystal X-ray analysis. Owing to the encapsulation effects, the accommodated acrylates do not undergo polymerization upon heating or UV irradiation, while they can be quantitatively extracted from crystals on demand by guest replacement with toluene.

Multifunctional Core–Shell-Structured Nanocarriers for Synchronous Tumor Diagnosis and Treatment In Vivo
Yin-Yin Chen, Ping-An Ma, Dong-Mei Yang, Yuan Wu, Yun-Lu Dai, Chun-Xia Li,* and Jun Lin*
Multifunctional mesoporous silica-coated upconversion luminescent/magnetic NaGdF4:Yb/Er@NaGdF4:Yb@mSiO2-PEG nanoparticles (designated as UCNPS) were fabricated through a phase transfer-assisted, surfactant-templating coating process, followed by hydrophilic polymer polyethylene glycol (PEG) functionalization to improve their stability and biocompatibility. The core–shell-structured composite nanomaterials can serve as an effective nanocarrier for synchronous tumor diagnosis and treatment.

First Isomers of Pristine C104 Fullerene Structurally Confirmed as Chlorides, C104(258)Cl16 and C104(812)Cl24
Shangfeng Yang,* Tao Wei, Erhard Kemnitz, and Sergey I. Troyanov*
Two of 823 topologically possible isolated-pentagon-rule C104 isomers, C1-C104(258) and D2-C104(812), have been confirmed for the first time through the X-ray crystallographic study of their chlorides, C1-C104(258)Cl16 and D2-C104(812)Cl24, respectively, whereas an admixture of C2-C104(811)Cl24 was assumed to be present in the latter chloride. (C102 + C104) fractions used for chlorination in glass ampoules with a VCl4/SbCl5 mixture were isolated in very small quantities (several dozens of micrograms) by multi-step recycling HPLC from an arc-discharge fullerene soot.

A Joint Photoelectron Spectroscopy and Theoretical Study on the Electronic Structure of UCl5- and UCl5
Jing Su, Phuong Diem Dau, Chao-Fei Xu, Dao-Ling Huang, Hong-Tao Liu, Fan Wei, Lai-Sheng Wang,* and Jun Li*
The UCl5- anion is produced using electrospray ionization and probed by photoelectron spectroscopy. Theoretical investigations reveal that the ground state of UCl5- is open-shell with two unpaired electrons occupying the U 5fz3 and 5fxyz based molecular orbitals. The structures of both UCl5- and UCl5 are confirmed to have C4v symmetry. Chemical bonding analyses on all the uranium pentahalide complexes UX5- (X=F, Cl, Br, I) indicate that the U-X interactions in UX5- are dominated by ionic bonding, with increasing covalent contributions for the heavier halogen complexes.
