However, it is shown that PCMs, which violate the octet rule, have two types of covalent bond: two-center, two-electron (2c-2e) bonds, and electron-rich, multicenter bonds (3c-4e bonds, hyperbonds) involving lone-pair electrons. The latter have bond orders less than one and are examples of the century-old concept of “partial” bonds.}, cin = {PGI-1 / IAS-1}, ddc = {660}, cid = {I:(DE-Juel1)PGI-1-20110106 / I:(DE-Juel1)IAS-1-20090406}, pnm = {5211 - Topological Matter (POF4-521)}, pid = {G:(DE-HGF)POF4-5211}, typ = {PUB:(DE-HGF)16}, pubmed = {37162226}, UT = {WOS:000984957200001}, doi = {10.1002/adma.202300836}, url = {https://juser.fz-juelich.de/record/1008446}, }
