Treatment of a white phosphorus with gallylene [Ar BIG -bianGa] (1) (Ar BIG -bian = 1,2-bis [(2,6-dibenzhydryl-4methylphenyl)imino]acenaphthene) in toluene affords [(Ar BIG -bianGa)2(μ-η 1 :η 1 -P4)] (2), containing the...
Reactivity studies on a pentanuclear nickel carbide reveal how its central carbide ligand allows exceptional stability, geometric flexibility, and controlled reactivity to enable highly selective catalysis.
Unsymmetrical, disubstituted ferrocene (FcH) compounds have a wide range of applications. However, their synthesis is challenging. In this work a straightforward approach for generating unsymmetric 1,1'-ferrocene derivatives is described and...
Organopnictonic acids are compounds with the general formula RPnO3H2 where Pn = P, As, Sb, Bi. They comprise a family of compounds with many useful properties and also provide a powerful framework for understanding fundamental periodic trends in bonding, structure, and reactivity across group 15. In this review, we present a comprehensive and critical perspective on phosphonic, arsonic, stibonic, and bismuthonic acids, covering the development of the field from its earliest foundations to the present day and, for the first time, unifying these oxyacids within a single conceptual framework. We describe the electronic and structural principles governing pnictogen-oxygen bonding, emphasizing the progressive attenuation of multiple bonding, and the growing propensity for hydrolysis, aggregation, and coordination sphere expansion on descending the group. The well-established chemistry of phosphonic and arsonic acids is treated concisely to enable direct comparison to the emerging experimental developments in the chemistry of stibonic and bismuthonic acids. By conducting a systematic comparison of phosphorus and arsenic systems with the evolving chemistry of antimony and the nascent exploration of bismuth analogues, we clarify fundamental constraints, expose unresolved questions, and map promising avenues for future progress in group 15 chemistry.
Chain coordination polymers are attractive for molecular luminescent thermometry due to their ability to promote efficient ligand-to-metal and interionic energy transfer while offering structural flexibility for tuning photophysical properties. Here,...
