The title compound, [FePt(CHOS)(CHP)(CHP)(CO)], , [(OC)Fe(μ-dppm)(μ-C(=O)C(CHSCHMe-4)=CCHSCHMe-4)Pt(PPh)], represents the first example of a diphosphane-bridged heterobimetallic Fe-Pt dimetalla-cyclo-pentenone complex resulting from a bimetallic activation of metal-coordinated carbonyl ligand with an inter-nal alkyne, namely 1,4-bis-(-tolyl-thio)-but-2-yne. The bridging μ-C(=O)C(CHSCHMe-4)=CCHSCHMe-4 unit (stemming from a carbon-carbon coupling reaction between CO and the triple bond of the alkyne di-thio-ether) forms a five-membered dimetalla-cyclo-pentenone ring, in which the C=C bond is π-coordinated to the Fe center. The latter is connected to the Pt center through a short metal-metal bond of 2.5697 (6) Å.

This perpective delves into the emerging field of matere bonds, a novel type of noncovalent interaction involving group 7 elements such as manganese, technetium, and rhenium. Matere bonds, a new member of the σ-hole family where metal atoms act as electron acceptors, have been shown experimentally and theoretically to play significant roles in the self-assembly and stabilization of supramolecular structures both in solid-state and solution-phase environments. This perspective article explores the physical nature of these interactions, emphasizing their directionality and structural influence in various supramolecular architectures.

The monoprotonated species of 2-aminomalonyl difluoride, namely, 1,3-difluoro-1,3-dioxopropan-2-aminium dihydrogen trifluoride, [CHFNO][HF], was synthesized from sulfur tetrafluoride in anhydrous hydrogen fluoride (aHF) with [NH][CHNO] as the starting material. The solvent was removed and the salt was dissolved in aHF and crystallized. In the solid state, the three-dimensional network is built by medium-strong N-H.

The layer-stacking mode of a two-dimensional (2D) material plays a dominant role either in its topology or properties, but remains challenging to control. Herein, we developed alkali-metal ion-regulating synthetic control on the stacking structure of a vinylene-linked covalent triazine framework (termed spc-CTF) for improving hydrogen peroxide (HO) photoproduction. Upon the catalysis of EtONa in Knoevenagel polycondensation, a typical eclipsed stacking mode (spc-CTF-4@AA) was built, while a staggered one (spc-CTF-4@AB) was constructed using LiOH.
