Hydrogen bonding in hydroxymethylphosphine chalcogenides. Inorganica Chimica Acta 335, 113-118.https://hdl.handle.net/10289/170Hydrogen bonding in the phosphine chalcogenide series Ph2P(X)CH2OH (X=O, 1; S, 2; Se, 3) has been investigated by single crystal X-ray crystallography. While the phosphine oxide exhibits a dimer motif, the sulfide and selenide form infinite chains; in all cases hydrogen bonding is from the OH group to the phosphine chalcogenide heteroatom. The trend in the hydrogen bond angle for OH X-P, which is 117, 87 and 84° for the oxide, sulfide and selenide, respectively, is explained with respect to the geometry of electron density on the phosphine chalcogenide heteroatom.enThis article is published in the journal Inorganica Chimica Acta, (c) 2002 Elsevier Science B.V.Crystal structuresHydrogen bondingPhosphine oxidePhosphine sulphidePhosphine selenideJournal Article10.1016/S0020-1693(02)00811-3
