The theoretical data for the half‐lantern complexes [{Pt(trueCN^ )(μ‐trueSN^ )}2] [1–3; trueCN^ is cyclometalated 2‐Ph‐benzothiazole; trueSN^ is 2‐SH‐pyridine (1), 2‐SH‐benzoxazole (2), 2‐SH‐tetrafluorobenzothiazole (3)] indicate that the Pt⋅⋅⋅Pt orbital interaction increases the nucleophilicity of the outer dz2 orbitals to provide assembly with electrophilic species. Complexes 1–3 were co‐crystallized with bifunctional halogen bonding (XB) donors to give adducts (1–3)2⋅(1,4‐diiodotetrafluorobenzene) and infinite polymeric [1⋅1,1′‐diiodoperfluorodiphenyl]n. X‐ray crystallography revealed that the supramolecular assembly is achieved through (Aryl)I⋅⋅⋅dz2 [PtII] XBs between iodine σ‐holes and lone pairs of the positively charged (PtII)2 centers acting as nucleophilic sites. The polymer includes a curved linear chain ⋅⋅⋅Pt2⋅⋅⋅I(areneF)I⋅⋅⋅Pt2⋅⋅⋅ involving XB between iodine atoms of the perfluoroarene linkers and (PtII)2 moieties. The 195Pt NMR, UV/Vis, and CV studies indicate that XB is preserved in CH(D)2Cl2 solutions.

The nature and structure of occupied and empty valence electronic states (molecular orbitals, MOs) of the [Ni(Salen)] molecular complex (NiO2N2C16H14) have been studied by means of X-ray photoemission and absorption...

Redox‐active nitroxyl‐containing polymers are promising candidates as possible replacements for inorganic based energy‐storage materials, due to their high energy density and fast redox kinetics. One challenge towards the implementation of such a system is the insufficient electrical conductivity, impeding the charge collection even with highly conductive additives. Herein, the first implementation of a polymeric bis(salicylideniminato) nickel (NiSalen) conductive backbone as an active charge‐collecting wire is reported. NiSalen simultaneously serves as a charge collector for nitroxyl pendants and supports the redox capacity of the material. This novel polymer exhibits a specific capacity of up to 91.5 mAh g−1, retaining 87 % of its theoretical capacity at 800 C and more than 30 % at as high as 3000 C (66 % capacity retention after 2000 cycles). The properties of the new material upon operation was studied by means of operando electrochemical methods, UV‐Vis, and electron paramagnetic resonance spectroscopy.

The half-lantern PdII 2 complexes trans-(O,C)-[Pd­(ppz)­(μ-O∩N)]2 (1) and trans-(E,N)-[Pd­(ppz)­(μ-E∩N)]2 (E∩N is a deprotonated 2-substituted pyridine; E = S (2), Se (3); Hppz = 1-phenylpyrazole) were cocrystallized with 1,4-diiodotetrafluorobenzene (FIB) to give cocrystals 1·(FIB) and (2−3)·2­(FIB); the parent complexes and the cocrystals were studied by X-ray crystallography. The crystal structure of trans-(O,C)-1·FIB is assembled mainly by the I···O halogen bonding (XB) to give the [@PdII 2]­O···I­(areneF)­I···O­[@PdII 2] linkage, while trans-(E,N)-(2–3)·2­(FIB) are built by the joint action of I···Pd and I···E XBs, thus furnishing the PdII 2···I­(areneF)­I···E­[@PdII 2] (E = S, Se) cluster. Detailed theoretical (DFT) studies with the application of the QTAIM, ELF, NBO, IGM, SAPT, and HSAB methods revealed several types of attractive noncovalent interactions in the cocrystals, namely, the I···Pd, I···E (E = O, S, Se), I···C, π–π-stacking, and π···F interactions. I···Pd is a rare type of XB involving the metal center as an XB acceptor, the Pd···Pd communication facilitating the I···Pd bonding. The I···Pd and I···E bonds are comparable in strength (the bond interaction energies being between −7 and −13 kcal/mol), but the former is controlled by dispersion forces, while the latter is mostly governed by an electrostatic term.

The improved ORR performance is attributed to the rich density of the Fe–Nx moieties derived from regulated coordination structures using dual-nitrogen-sources.
