Summary: We describe a mixed organic cationic hybrid nitrate, [C(NH2)2NHNO2][C(NH2)3](NO3)2 (1), which was synthesized by combining three different planar groups: [(C(NH2)2NHNO2]+, C(NH2)3+, and NO3-. First-principles calculations demonstrate that the [(C(NH2)2NHNO2]+ group is an excellent cationic nonlinear-optical (NLO)-active unit. The compound exhibits a moderate second-harmonic-generation (SHG) response (1.5 x KDP), a wide band gap (3.58 eV), and a suitable birefringence of 0.071 at 550 nm. Theoretical calculations indicate that the synergy effect between the [(C(NH2)2NHNO2]+ and C(NH2)3+ groups dominates the SHG process.

Summary: In this study, new electrocatalysts based on 2D anion-intercalated metal hydroxides of Ni-2(OH)(2)(NO3)(2) (2D NiHN) and its derivation caused by the implantation of single platinum atoms (Pt-SA-2D NiHN) are reported. The Pt-SA 1.73-2D NiHN material shows promising HER activities with low Pt loading, while the 2D NiNH requires a higher overpotential for OER.

Summary: Reactions between lanthanide ions and benzene-1,3,5-tricarboxylate in water at ambient conditions result in two series of iso-structural coordination polymers. The luminescence properties of these polymers were studied, and it was found that heavy lanthanide ions form non-luminescent polymers. Molecular alloys belonging to the non-luminescent structural families were obtained using a phase induction strategy and showed significant emission. Solid-state NMR spectroscopy experiments confirmed the random distribution of lanthanide ions in these alloys. The study suggests the importance of exchange-based intermetallic energy transfer mechanisms and intermetallic exchange pathways through pi-stacking interactions in these systems.

Summary: This study demonstrates the assembly and transfer of single-chain magnets (SCMs) in the gel phase. SCMs based on Tb-III ions and nitronyl-nitroxides radicals with short alkyl chains can form crystalline supramolecular nanotubes interacting with heptane to create a robust gel. The gel is composed of supramolecular nanotubes, as confirmed by small-angle X-ray scattering, and exhibits SCM behavior in magnetism. Gelation on the surface allows for the deposition of supramolecular nanotubes as thick films or sub-monolayers.

Summary: In this study, the thermodynamics of lanthanide-based coordination polymer molecular alloys were investigated. It was found that the solubility of homo-lanthanide-based coordination polymers can vary significantly among different lanthanide ions.

Summary: Coordination-driven supramolecular syntheses between flexible precursor A and pseudo-halide ions resulted in the selective formation of discrete Cu-8 assembly D and one-dimensional coordination polymer E. Subsequent reactions with M'(II) salts led to the self-dissociation and reorganization processes, yielding new discrete Cu-8 assemblies. The solid-state luminescence properties of these derivatives showed D as a moderate room temperature luminophore, while E, F-Zn, and F-Cd exhibited weak luminescence at low temperature.
