Cu (I) and Ag (I) complexes of the fluorinated triazolate ligand [3,5-(C3F7)2Tz](-) have been synthesized using the corresponding metal(I) oxides and the triazole. They form pi-acid/base adducts with toluene, leading to [Tol][M3][Tol] ([Tol]=toluene; [M3]={[3,5-(C3F7)2Tz]Cu}3 or {[3,5-(C3F7)2Tz]Ag}3) type structures. Packing diagrams show the presence of extended chains of the type {[Tol][M3][Tol]}infinity, but the intertoluene ring distances are too long for significant pi-arene/pi-arene contacts. These copper and silver triazolates react with PPh3 (at a 1:1 metal ion/P molar ratio), leading to dinuclear {[3,5-(C3F7)2Tz]Cu(PPh3)}2 and {[3,5-(C3F7) 2Tz]Ag(PPh3)}2. They feature a six-membered Cu(mu-N-N) 2Cu or Ag(mu-N-N)2Ag core with a boat conformation.

Porous organic cages (POCs) and metal-organic polyhedra (MOPs) function as zero-dimensional porous materials, able to mimic many functions of insoluble framework materials while offering processability advantages. A popular approach to access tailored metal-based motifs in extended network materials is postsynthetic metalation, which allows metal installation to be decoupled from framework assembly. Surprisingly, this approach has only sparingly been reported for molecular porous materials.

A series of structurally similar trinuclear macrocyclic copper(I) and silver(I) pyrazolate complexes bearing various short-bite diphosphine RPCH(R')PR ligands are reported. Upon diphosphine coordination, the planar geometry of the initial complexes undergoes bending along the line between two metal atoms coordinated to the phosphorus moieties. The complexes based on dcpm ligands (R = cyclohexyl, R' = H, Ph) do not exhibit dynamic behavior in solution at room temperature on the P NMR time scale as it was previously observed for similar trinuclear copper complexes bearing the dppm (R = Ph, R' = H) scaffold.

The imidazole alkaloid lepidiline A from the root of has a moderate to low in vitro anticancer effect. Our aim was to extend cytotoxicity investigations against a panel of cancer cells, including multidrug-resistant cancer cells, and multipotent stem cells. Lepidiline A is a N-heterocyclic carbene precursor, therefore a suitable ligand source for metal complexes.

Article Synopsis
- Heteroleptic silver(I) complexes are gaining attention for thin-film lighting technologies due to their lack of distortion during excitation compared to copper(I) complexes.
- This study focuses on a specific Ag(I) complex with N-heterocyclic carbene and 2,2'-bipyridine that shows strong green emission due to intermolecular interactions and aggregation-induced emission.
- Although the complex demonstrates poor emission in thin-film form, it has excellent electrochemical stability under operating conditions, suggesting promising applications in lighting devices.

This study was focused on the activation of the CP bond reactions of PhCP-PBu (1) with 1,6-hexanediol and selected dithiols (1,4-butanedithiol, 1,4-benzenedithiol and 1,4-benzenedimethanethiol). These reactions proceed according to a 1,2-addition mechanism, providing new compounds with formulas {(Ph)(H)C-P-PBu}{μ-(O-(CH)-O)}{BuP-P-C(H)(Ph)} (2), {(Ph)(H)C-P-PBu}{μ-(S-(CH)-S)}{BuP-P-C(H)(Ph)} (3a), {(Ph)(H)C-P-PBu}{μ-(S-CH-S)}{BuP-P-C(H)(Ph)} (3b), and {(Ph)(H)C-P-PBu}{μ-(S-CH-CH-CH-S)}{BuP-P-C(H)(Ph)} (3c). Next, the reactions of 3a and 3c with metal chlorides led to the growth of desired coordination polymers of copper(I) and silver(I).
