“…More surprising than the mono-deprotonation of 2c is that double deprotonation can be effected to access the arsenido complex 4, adding to a class of metal-ligand multiple bonds previously limited to the d-block [62][63][64] . Uranium(IV) generally forms more polarized multiple bonds with ligands than uranium(V) or (VI), so any uranium(IV)-ligand multiple bond would be expected to be reactive and weak.…”

“…Reports of a terminal M=AsH unit in the p-block are restricted to one example in a silylidenearsane/arsasilene with a HSi=AsH subunit 61 . The (As) 3− arsenido is rare in a molecular context and only four terminal arsenidos with group 5 and 6 d-block metals are known [62][63][64] . AsH n fragments are key intermediates in metal organic chemical vapour deposition materials processes, so studying metal derivatives is germane to understanding their properties.…”

To further our fundamental understanding of the nature and extent of covalency in uranium-ligand bonding, and the benefits that this may have for the design of new ligands for nuclear waste separation, there is burgeoning interest in the nature of uranium complexes with soft- and multiple-bond-donor ligands. Despite this, there have so far been no examples of structurally authenticated molecular uranium-arsenic bonds under ambient conditions. Here, we report molecular uranium(IV)-arsenic complexes featuring formal single, double and triple U-As bonding interactions. Compound formulations are supported by a range of characterization techniques, and theoretical calculations suggest the presence of polarized covalent one-, two- and threefold bonding interactions between uranium and arsenic in parent arsenide [U-AsH2], terminal arsinidene [U=AsH] and arsenido [U≡AsK2] complexes, respectively. These studies inform our understanding of the bonding of actinides with soft donor ligands and may be of use in future ligand design in this area.

“…Reaction of the thorium butadiene complex (η In contrast, activation of molecular arsenic by homogeneous transition metal complexes is considerably more diverse; formation of cyclo-Asn ligands (n = 3-6, 8) [54,148], metal arsenic clusters [149], coordination of intact As4 tetrahedra to metal ions [133,150,151], fragmentation into As2 and other As4 ligands [152][153][154], catenation to As10 and As12 ligands [155], reactions to form PnAsm ligands [156], and full As4 fragmentation resulting in terminal M≡As arsenide bonds [157] have all been reported.…”

“…Reaction of As 4 (generated in situ by heating grey arsenic metal) with Mo(N[ t Bu]3,5-Me 2 -C 6 H 3 ) 3 has been shown to produce the terminal arsenide complex Mo(RAs)(N[ t Bu]3,5-Me 2 -C 6 H 3 ) 3 . 67 Tetrahedral As 4 has also been employed as a precursor for 62 which contains an Nb 2 As 2 butterfly core. 68 Reduction of 62 affords the terminal arsenide anion complex 63 which, on reaction with ClPQNMes*, gives 64.…”
