It is proposed that this structure is stabilized by five-center/six-electron (5c-6e) hypervalent interactions.||Type of material:||Journal Article||Publisher:||Royal Society of Chemistry||Journal:||Chemical Communications||Volume:||49||Issue:||14||Start page:||1434||End page:||1436||Copyright (published version):||2012, Royal Society of Chemistry||Keywords:||Multicentre hypervalent interaction; Bridged linear cations; Phosphonium dihalides; Trihalophosphonium dications; Chemical bonding||DOI:||10.1039/c2cc38363b||Language:||en||Status of Item:||Peer reviewed|
