{"doi":"10.1002/chem.202201144","title":"Binding, Release and Functionalization of Intact Pnictogen Tetrahedra Coordinated to Dicopper Complexes","abstract":"Abstract The bridging MeCN ligand in the dicopper(I) complexes [(DPFN)Cu 2 (μ,η 1 : η 1 ‐MeCN)][X] 2 (X=weakly coordinating anion, NTf 2 ( 1 a ), FAl[OC 6 F 10 (C 6 F 5 )] 3 ( 1 b ), Al[OC(CF 3 ) 3 ] 4 ( 1 c )) was replaced by white phosphorus (P 4 ) or yellow arsenic (As 4 ) to yield [(DPFN)Cu 2 (μ,η 2 : η 2 ‐E 4 )][X] 2 (E=P ( 2 a – c ), As ( 3 a – c )). The molecular structures in the solid state reveal novel coordination modes for E 4 tetrahedra bonded to coinage metal ions. Experimental data and quantum chemical computations provide information concerning perturbations to the bonding in coordinated E 4 tetrahedra. Reactions with N‐heterocyclic carbenes (NHCs) led to replacement of the E 4 tetrahedra with release of P 4 or As 4 and formation of [(DPFN)Cu 2 (μ,η 1 : η 1 ‐ Me NHC)][X] 2 ( 4 a,b ) or to an opening of one E−E bond leading to an unusual E 4 butterfly structural motif in [(DPFN)Cu 2 (μ,η 1 : η 1 ‐E 4 Dipp NHC)][X] 2 (E=P ( 5 a,b ), E=As ( 6 )). With a cyclic alkyl amino carbene ( Et CAAC), cleavage of two As−As bonds was observed to give two isomers of [(DPFN)Cu 2 (μ,η 2 : η 2 ‐As 4 Et CAAC)][X] 2 ( 7 a,b ) with an unusual As 4 ‐triangle+1 unit.","journal":"Chemistry - A European Journal","year":2022,"id":258664,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":17,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9446,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":311759,"name":"Amélie Nicolay","orcid":"0000-0002-0495-2055","position":1,"is_corresponding":false},{"id":910744,"name":"Maria Haimerl","orcid":null,"position":2,"is_corresponding":false},{"id":910235,"name":"Michael Seidl","orcid":"0000-0002-5218-2083","position":3,"is_corresponding":false},{"id":910236,"name":"Gábor Balázs","orcid":"0000-0003-3497-7082","position":4,"is_corresponding":false},{"id":292449,"name":"T.
