Abstract Two new trinuclear μ 3 ‐bridged rare‐earth metal phosphinidene complexes, [{L(Ln)(μ‐Me)} (μ ‐Me)(μ ‐PPh)] (L=[PhC(NC 6 H 4 i Pr 2 ‐2,6) ] − , Ln=Y ( a ), Lu b )), were synthesized through methane elimination of the corresponding carbene precursors with phenylphosphine. Heating toluene solution at 120 °C leads to an unprecedented ortho CH bond activation PhP ligand form bridged phosphinidene/phenyl complexes. Reactions ketones, thione, or isothiocyanate show clear phospha‐Wittig...

Multifunctional additives are widely utilized in enhancing the performance of perovskite solar cells, and role is highly related to contained various functional groups. Here, we introduce a pair geometric isomers, which act as bifunctional with terminal −NH3+ group −COOH group, into methylammonium lead iodide perovskite. Surprisingly, although two share exactly same groups, find that they play opposite roles crystallization process. The systematical investigation indicates only trans...

Rare examples of molecular, dinuclear CeIII and PrIII complexes with robust Ln-coordination are accessible by use the tetraphenolate pTP as a supporting, chelating O-donor ligand platform, = [{2-(OC6H2R2-2,4)2CH}-C6H4-1,4]4- that favours higher formal oxidation states to rare earths. Two classes have been made from platforms; one metallacyclic 2 + [Ln2(pTP)2] framework rigid, letterbox-shaped geometry [Ln(aryloxide)4] core, more flexible [(LnX)2(pTP)] earth ion at either end platform.
